Three days ago on a hot afternoon i went to go pick up my spouse from work. I had the car in parked, the engine running and the ac running high for 30mins all of a sudden my car shook and the engine turn off when it did i saw a green key light on for a second before the car went dead. At that time i didn't know what it was so i just let it off and remove my key for a good 10mins then i turn it on and the car start but feel like it can't get full energy so i had to step on the gas pedal a few time. Drove around the parking lot for several minutes and went to go park again since the spou
Experienced mechanics share their insights in answering this question :
Hi There,
A few different things will usually cause the car to start and then die. A bad ignition coil can cause this if it is beginning to fail, resulting in intermittent starting problems. A dirty or faulty mass air flow sensor, may also cause this kind of reaction. The mass air flow sensor is a unit that measures the volume of air entering the motor and relays this information to the computer in order to cause the computer to make the proper air/fuel adjustments. A bad fuel pump or fuel pump relay may also cause this kind of starting issue as a result of the engine starving for fuel. The immobilizer light will come on when any of these happen as the car’s computer detects irregular patterns in the vehicle engine operation. I would suggest having a professional from YourMechanic come to your location to diagnose and inspect your vehicle to determine the proper solution to this.

Other generally common reasons for a Check Engine Light are dirty mass airflow sensor, broken oxygen sensor, a malfunction with the fuel injection system, broken head gasket, broken emissions control part, or defective spark plugs to name a few.

A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it`s in good condition. If you have a tank of bad gas in the car, your check engine light may come on.
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.
The rule of thumb is that if the check engine light is flashing, you can`t keep driving the car. It`s an emergency. Often it indicates an engine misfire. If you keep driving, you will likely cause irreversible damage, mostly to the (expensive) catalytic converter.
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.
A steady check engine light indicates a non-emergency issue, such as a loose gas cap. Flashing check engine lights warn of severe situations requiring immediate attention. Standardized diagnostic codes help identify the trouble.
Will the check engine light reset itself? The check engine light on your Honda will usually shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it`s tightened, the light will turn itself off.
2) Turn Your Car On and Off

Another way to reset the check engine light code that Marshall drivers can try is to turn the car on for about a second and then turn it off. Doing this will cause most vehicles to reset the trouble codes and the check engine light will turn off.

These problems can range from faults within the electrical system, the engine, fluid levels or to problems within the car`s emissions system. The problem can even be as simple as forgetting to tighten your gas cap – in fact, this is the most common reason why check engine lights appear in the first place.
An illuminated check engine light is the first warning sign that your vehicle needs an oil change. It can activate because the oil is too dirty or when there`s not enough flowing throughout the engine.
How long can you drive with the check engine light on? Once you see the check engine light, it is safe to drive with the light on for 50 to 100 miles. This is because if the issue is with the sensors, then this will buy some time for it to reset, turning the check engine light off.
A flashing orange light means that there is a problem that could affect how the car drives or handles, such as an engine misfire. You might be able to feel your car shake, or the engine could suddenly sound different. If this light comes on, you should take your car to be inspected immediately.
A bad battery can cause problems in electrical and electronic parts, including the computer. It can even cause a “Check Engine” light.
All the problems that could trigger a check engine light are serious. If the check engine light comes on, it`s one dashboard light you should not ignore. Whether for a week, a month, or a year, if you ignore the check engine light, it puts your vehicle, and by extension, your personal safety at risk.
The “check engine” light is the onboard diagnostic system`s way of telling you something`s wrong. But that something could be one of many things, big or small. It could pop on because of something minor like a loose or faulty gas cap. It could also mean a major engine failure.
If the check engine light illuminates, it will either blink or remain constantly illuminated, depending on the problem. A blinking light, or in some cars a red light instead of a yellow or orange light, indicates a problem that needs immediate attention. Either way, you should have the vehicle checked by a mechanic.

To make sure the check engine light does not reappear, it`s recommended that you drive your car 30 to 100 miles. This enables the vehicle`s “Drive Cycle” to reset, as the various sensors need time to recalibrate.
Press the odometer`s Trip and Reset buttons while turning the ignition key ON. After turning the key ON, release the odometer Reset and Trip buttons to check if the Diagnostic Trouble Code or DTC appears on the odometer display.
If the engine is running rough or your check engine light illuminates, the cause may be excess oil contacting the spark plugs and causing a misfire.
And while the old rule of thumb was to change your oil every 3,000 miles or so, modern automotive technology has stretched that figure even further. Due to better engineering and better oil formulations, now you can expect between 7,500 to 10,000 miles between oil changes!
Extreme cold weather can make your car battery work harder for your car not just to start, but also to continue operating. Signs of a dying/dead battery include: Engine is slow to crank (i.e. start up) or won`t crank at all. “Check engine” light is on.

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.
