Hi and thanks for your question. Sounds like there could be a fuel or spark issue with your engine. First you would need to scan the computer for what the engine light code has stored to have a starting place to work on. If the code comes back for a battery disconnect P1684 then there could be an issue with the battery cables or a connection to the starter or on the ground of the vehicle. If there is a code for fuel injector high resistance P0201 – P0206, then an injector could be plugged/failed or the harness to the injector could have gotten disconnected. With one at a time, remove each harness to the injector with the engine running and see if the engine stumbles. If the engine stumbles then that injector is working. If there is no change then that injector is not functioning. Check for power and ground at the plug to make sure that the injector is being activated. The last thing to check is the spark plugs and to make sure that they are in good shape and not burned or full of oil. If you need assistance in troubleshooting your engine shut off issue, then seek out a technician, such as one from YourMechanic, that can help you with your vehicle.
How to Identify and Fix Common car Problems ?

Common reasons for this to happen:
Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine.
If the check engine light in your Chrysler 300 starts flashing, that means that the problem needs immediate attention and your Chrysler should be brought in instantly. A flashing light hints that the problem is strict and if not taken care of instantly may result in major damage to the vehicle.
Low transmission fluid or a broken torque converter, which doesn`t give the transmission enough power to shift. Low fuel. Broken fuel pump or fuel injectors, which means that the gas isn`t reaching the engine. Corrosion on the battery cables or terminates which prevents your battery from charging through the alternator …
When your engine shuts off when you slow the car down its often as a result of a: Malfunctioning transmission. Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump.
Cars shouldn`t shut off while driving, but when they do, the most common culprits are: A bad crankshaft position sensor. Other sensor issues in the engine. A faulty fuel system.
A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air. A thermostat that is stuck closed will cause the vehicle to overheat.
While the check engine light can definitely be indicative of serious problems, the most common cause of the flashing is usually an engine misfire. There are many reasons why an engine misfire might be occurring. To run smoothly, an engine must be receiving the correct amount of power from the cylinders in your vehicle.
Owners of Chrysler 300 vehicles complain about various transmission defects as well as fluid leaks that often lead to larger transmission problems. If it is not repaired, a fluid leak may lead to severe long-term damage to the Chrysler engine.
Also known as `limp home mode`, limp mode is a security feature in cars which activates when the engine or transmission control unit picks up a fault. Once it detects a problem, limp mode will cause the less important parts of the car, such as air conditioning, to switch off, and the speed of the car will be reduced.
A non-functioning catalytic converter can cause your engine to suddenly and inexplicably shut off, or even refuse to start. This can be a serious safety hazard, as your vehicle could turn off while you are driving because the catalytic converter is not venting emissions quickly enough.
Sometimes, the check engine light comes on to let you know that there`s a problem with the car`s internal diagnostic mechanism. That means the system could be “finding” a problem that doesn`t exist, or it could be that loose wire systems are creating a false positive in the system.
In most cases, successfully repairing the issue that caused your light to come on will cause the check engine light to turn off automatically—but only after 10 to 20 “cycles”. A cycle, in this instance, refers to the process of turning the vehicle on, running it for some time, and turning it off again.
Many modern vehicles are designed with several fail-safes to help protect the engine in adverse conditions. One of this is an automatic shutoff when the oil pressure drops to a certain level, or the oil level drops too low (note that this is not true for all cars). This causes the engine to stall and die.

When your transmission doesn`t have enough fluid, you may experience it stalling at red lights or stop signs. Though it should start right back up, taking your car to an auto shop for repair is key as your transmission lines may be leaking and may need to be replaced.
Your vehicle may be equipped with an engine idle shutdown system. This system automatically shuts down your engine when it has been idling in P (Park) or N (Neutral) for five minutes (parking brake set) or 15 minutes (parking brake not set).
The thermostat is responsible for regulating the engine`s operating temperature, and if it fails to do so, it can cause the engine to overheat. When the engine overheats, it can cause damage to the transmission, such as boiling the transmission fluid, which can lead to transmission failure.
A failed O2 sensor is the most common cause of a flashing check engine light. The O2 sensor is a critical part of the exhaust system, monitoring how much unburned oxygen is exiting the engine in the exhaust. The sensor sends messages back to the engine to adjust the mix of oxygen and fuel being used.
So how do you know when you have an emergency? You can judge how serious an issue is by looking at the warning light. The check engine light can show up in two ways: Solid yellow/amber light: Indicates a less urgent issue. Flashing light or red: Indicates a severe problem that needs immediate attention.
Intermittent flashing of your check engine light occurs when your engine experiences what`s called either an “intermittent failure” or “soft failure.” Soft failures are caused by engine problems that need certain conditions to appear. The most common example of an intermittent failure is that of broken wires.
The most common causes of misfires are worn, improperly installed, and mishandled spark plugs, malfunctioning ignition coils, carbon tracking, faulty spark plug wires and vacuum leaks.
A Blinking Light is Bad
In most cases, a check engine light will shine steadily, a serious reminder that something is amiss in your vehicle. If the light is blinking, however, your minor annoyance and concern just got elevated. If the check engine light is blinking, get to the nearest trustworthy mechanic you know.
The most common problems found in the 2006 Chrysler 300 include engine failures, the gear shifter getting stuck in park, and transmission issues. Engine failures are the most common complaint from owners at around 100,000 miles.
The most common reasons a Chrysler 300 engine stalling are the fuel system, the air intake system, or the ignition system. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
How to get your car out of limp mode. You may be able to reset the car by switching it off and on again after about 30 seconds. If the warning lights disappear and the car behaves normally, then it may have just been a temporary glitch.

2012 equinox reduced power light engine light and traction light came on. Lost a lot of power got home and all light except engine
ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.
My Hyudai elantra 2014 stalled and stopped after the battery light, engine light and oil light came on
ANSWER : Hello, thank you for writing in. With check engine lights on, the first step is always scanning the vehicle for codes. These help direct your attention and ease diagnostics. The main concern is that the engine is making a loud noise. We need to determine if the noise and the battery or oil light are related. A major issue with the engine would effect the alternator charging the battery, the oil pressure, and several other components. However issues with the drive belt and other components can play a factor as well. Electrical and charging issues can cause various sensors to fail, and cause other warning lights to turn on. Only further inspection will tell, and you may need to get a second opinion. For help from our technicians, contact our service department to schedule an appointment.
Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.
Honda Civic 2008. AC stopped working suddenly and engine check light came ON for a day.Next day AC worked and no engine light.
ANSWER : Hi there. In both cases, when an AC system is not working and a warning light is coming on the dashboard, typically a professional mechanic will complete the same initial inspection, which is to download the stored error codes that triggered the warning light initially. This tends to give them an idea as to what is causing the problems. This could be something as simple as an electrical relay that is faulty or loose or an indication of a computer related "glitch". Either way, the best way to move forward is to have a professional mobile mechanic complete a check engine light inspection.
Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
ANSWER : Hi there. It is possible that the battery cable came loose or the wires to the oil pressure sensor has came loose or failed. Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken. If everything looks good, then the oil pressure sensor may have failed. Plus, check the computer for codes and see what is stored. This will lead you to the part that could have failed. I recommend replacing the oil pressure sensor then checking to see if the lights will go out. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the warning lights that came on.
Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.
Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.
To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.
my check engine light came on a few weeks ago and said it was coolant issue light went out and a few days ago it came back on
ANSWER : Your vehicle has less than 60,000 miles and inasmuch as you mention a possible fault in the engine cooling system, you should check for warranty coverage under Chrysler’s 5 year/60,000 miles powertrain warranty. If you are not covered under the manufacturer warranty, I recommend you request an overheating diagnostic from YourMechanic simply because a car that is overheating is essentially inoperable. You will ruin the engine if it gets hot enough, by warping essential engine components, so overheating has to be resolved before the issue with the electronic throttle is addressed. In your case, inasmuch as the Check Engine Light (CEL) has come on as well, the Mechanic will download the diagnostic trouble codes that always set when the CEL illumuninates and use those trouble codes as clues to resolving the issue you are having.
