hi , i have a 2004 g35 infinity , on my way to work when slowing down or at a red light my car sensor lights all came on the then

my car is stalling at red lights or when i slow down and all the sensor and service engine lights come on then when cranking it back up it seems like its taking longer to roll over

My car has 180000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hey there. Your car’s sensor lights come on when there is something not functioning properly which is likely related to the car stalling. The car may stall for a wide variety of reasons such as going into "Limp Mode" which is something the car’s computer does when it senses something I not functioning properly. The reason for this is more of a safety measure in an effort to keep you and car safe and to not cause additional damage. The stalling may be related to failing throttle position sensor, mass air flow sensor, crankshaft position sensor, camshaft position sensor or potentially failing ignition coils. I would recommend having an expert from YourMechanic come to your home to diagnose this using a scanning tool which will download critical data from the car’s computer related to the sensor lights coming on. This data will help indicate what the potential issues may be.

How to Identify and Fix Common car Problems ?

The purpose of the service engine soon light is to alert drivers that the car`s sensors have detected some sort of malfunction. These sensors are often triggered by issues with the emission control system of the vehicle, but there can be a variety of different causes.
The “Check Engine” or “Service Engine Soon” light indicates there may be a repair or replacement of your engine or transmission. It means there is more than a routine repair or service requirement, and instead, a system failure to the fuel, transmission, ignition, or emissions.
Sometimes an engine warning light can come on for something as simple as contaminated gas. This should go away after the car has worked through one or two tanks of good gas, but if you`re unsure, have the car hooked up to a diagnostic reader to check.
Can you drive a car with the engine light on? It`s okay to drive for a few miles, but be sure to schedule an inspection of the engine as soon as possible. If the check engine light comes on while you`re driving, don`t panic! Pay attention and see if the car is driving any differently than normal.
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.
If the check engine light in your INFINITI starts flashing, that means that the problem needs attention promptly and your INFINITI should be brought in swiftly. This blinking light usually indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system.
The simplest explanation for the difference between a check engine light and service light is the former indicates a major problem and the latter indicates a need for maintenance or regularly scheduled service.
Fully depress the accelerator pedal and keep it for more than 10 seconds. Fully release the accelerator pedal (The CEL light will continue to blink). Turn ignition switch to “OFF” position and now you can start the car.
A check engine light will shut itself off if the condition that caused it is remedied. So, if your converter is marginal, and you did a lot of stop-and-go driving, which creates high demand for the converter, that may have turned on the check engine light.
Just start the engine, wait for a second or two, and then turn it off—three times. Restarting the car 3 times forces the car`s computer to re-evaluate the issue and determine whether the problem still persists. The Check Engine Light should disappear if the issue has been resolved.
This means that more than one problem could be causing your check engine light to illuminate. Perhaps the technician replaced your oxygen sensor, but your engine also needs some spark plugs to be replaced. The best course of action here is to take your car to the technician again to see what else needs to be done.
The reasons for a check engine light turning on can range from something minor like a loose gas cap to something more serious like a faulty catalytic converter. It could even be a sign of internal engine failure. Ignoring the problem can turn a potentially quick fix into a costly and time-consuming repair.
When the check engine light is solid, you can typically drive the car for hundreds of miles without an issue. Of course, that depends on which code is stored in the vehicle`s computer. If an engine sensor is faulty, the car will usually use made up sensor values to keep running.
If the check engine light in your INFINITI starts flashing, that means that the problem needs attention promptly and your INFINITI should be brought in swiftly. This blinking light usually indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system.

My car stalls at times, yesterday the car shut off at a red light. I turned car off then back on now engine light is on.
ANSWER : This may be a result of a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle. Since this valve is controlled by the vehicle’s computer, it will adjust idle speed based upon other measurements such as engine temperature, intake air temperature and electrical system load or voltage. When you accelerate, the engine RPM increases, and as you let off the gas, the RPM slowly returns to the normal idling speed with the help of the idle air control valve making the transition from a higher RPM back down to idle speed. When the engine RPM drops below the normal range of about ~800 RPM, this often times will cause the engine to stall indicating a dirty or faulty idle air control valve. I would recommend having an expert from YourMechanic come to your location to diagnose and replace your idle air control valve.

All dashboard lights and tail lights do not work after driving through a lot of snow. Headlights work. And brake lights work.
ANSWER : Hello. We’ll be happy to help you. There are a few things that I recommend checking to discover why your lighting system is malfunctioning. The headlight dimmer switch should be checked. Along with the wiring harness above the right front tire behind the fender well cover. Also
the main fuse under the hood should be inspected because other people with your particular vehicle have had similar lighting issues if that fuse goes bad. It will be a great idea to check the rest of the fuses in that area too while checking the main fuse. Once the fuses are checked inside of the main fuse box then I would check the fuses inside of their interior fuse box. The interior fuse box should be located on the driver side of the dashboard near where your legs would be.

Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.

I was driving and my car started to slow down, and my gas pedal wouldn’t work, and all the signs came on and the car light was flickering
ANSWER : Hi, thanks for writing in. It sounds like your battery has crashed. When the system voltage drops below a certain point, the electronics go haywire. The alternator is supposed to maintain the battery voltage at around 14 volts, and I’m guessing that your’s is not working. When the alternator stops charging, the car can continue to run on stored energy in the battery for a few hours, until the voltage falls below about 10 volts, then all those crazy things start happening.

It’s hard to say without hearing it, but the "airplane" noise may be coming from your failed alternator. I don’t recommend running out and buying a new alternator right away, the battery needs to be fully charged or replaced so that you can have a proper tests performed.

Charging or installing a battery, or even jumping one off, is a risky business on a modern car. Connecting the cables incorrectly for even a moment can do a lot of expensive damage to the various modules in your car.

I would recommend having an expert from YourMechanic come to your home or office to confirm a diagnosis on the issue and make or suggest the necessary repairs or replacements.

My dash board don’t work my front light work when I change my light into high beam and my back window won’t go down
ANSWER : As unfortunate as it is, your vehicle would be considered flood damaged. Diagnosing electrical problems in a flood damaged vehicle is nearly impossible. This would take many hours or even days to determine which wiring harnesses and circuits have been affected. Then nearly all of the wiring under the dash would likely require replacement as well as many sensors and switches. On a BMW vehicle, the amount of wires and switches are likely more than that of a lower end vehicle. Due to the inefficiency in cost, you would likely be able to purchase another BMW like yours for less than what it would cost to fix your car. Many insurance companies would consider this type of damage to total out the vehicle unfortuantely.

Dash, Tail/brake, dome, trunk, glovebox, and door lights won’t work, dash doing weird things.
ANSWER : Hi there. Sure would appear a lot is going on electrically all at once. This could be, a problem in the PDC (power distribution center). The PDC is typically located under the hood and contains numerous fuses and relays. I don’t believe any one fuse will resolve all of the electrical issues. There is a possibility, it is not a power supply issue. It may be, the result of a poor electrical ground common to the inoperative components. Proper circuit testing should be performed. This would confirm the cause of multiple electrical failures. I recommend having your vehicle’s electrical problems be diagnosed and repaired by a certified technician, such as one from YourMechanic.

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.
