You will find more times than not when the check engine light comes on it is going to be an emissions problem, specially since the problem does not seem to be very noticeable, im guessing probably O2 sensor maybe even a Vaccume canister, the best way to find out why the engine light is on is to go down to your local auto store and rent not buy but rent a OBD2 scanner you hook this to the OBD2 port located under your drivers side dash usually to the left plug it in and follow the instructions that the scanner gives you it will then tell you what system sometimes even what part is going wrong with your vehicle, but I can almost promise you it is going to be something to do with emissions.

My 2002 dodge Durango drives fine there are no check engine light on but lately while driving on expressway it starts to shutter and then it turns off.. I try and start and it won't, wait a while and it...


Many times check engine lights are disabled to prevent them coming on. Turn the ignition on without starting the engine, the light should be on. Most auto parts stores will do an OBS2 check free to diagnose problems.

Check engin light stays on. Starts fine runs


Most common cause of engine lights is either an air fault such as air flow meter or air mass sensor. there are others but if the car is driving fine then most likely an air fault.

Check the air sensor sometimes they just need a clean up rather than replacement.
Let me know if you need more info.

Trac off and check engine light for lexus es 300 check engine & trac control off lights & engine stutters while revving in park. Engine seems fine in drive... Reset lights without them returning...


A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on. Both "Check Engine" and "Trac Off" lights were still on.

The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. So, I got a new battery from Costco ($59) and put it in. It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time.

The next morning, when I turned the car on, there was no problems. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly.

2009 ford fusion engine light stays on steady


You just have to disconnect the battery for 1/2 hour. then reconnect and drive for 10 miles so computer can relearn your engine again. It may run rough. You should have the key off when refueling because computer sensed a fuel vapor leak during fueling and turned the light on.

Also, you can always drive with a check engine light on. It just means you are not meeting emissions. Do not drive if it's flashing on and off.
