2003 GMC Envoy Why would your check engine light come on after starting on a VERY cold day I tried starting it a few times to no luck after it warmed up a bit it started but the engine light is on?

Drive it for a few days and log some miles on it and the check engine light may go out. Mine used to set a check engine light on really hot days here in the desert. I was told then engine and the computer have to go thru x amoutn of cycles and if the problem doesn't show up during those cycles, the check engine light will turn off. Enevtually the light came on to stay and my problem turned out to be a weak fuel pump.

Check engine light on 2001 s500?

I just bought a 2001 s500. The person I bought it from told me that if I let the gas get too low or did not tighten the gas cap properly, the "check engine" light would come on. Well, about two weeks after I purchased the vehicle I let the gas get a little low and sure enough the "check engine" light came on. I filled it up with gas and the "check engine" light stayed on. I got worried. Finally after two days of being on it just went out by itself. Has not come back on since.


Why does my 1996 Sunfire heater deliver cold air on cold days?

Check your temperature gauge. If it shows the engine is running in the normal range then there could be a problem with the "air door" that controls how much air is brought in through the heater core. Or the core itself is plugged and needs to be flushed out. If the guage shows the engine is running cold , then you should have the thermostat replaced.

Why does the check engine light come on when I get gas then go off after driving the car for a few days?

Basically if the check engine light goes off it means the fault is not permanent and not consistent. The fault came and after so many cycles the PCM said there's a problem and it lit up the check engine lite. After so many cycles of the fault correcting itself the PCM then stopped the light from being on. Nevertheless the PCM always usually records this fault in its history of faults for retrieval later on via a scanner == I have heard that sometimes if the gas cap is not on tightly, or the door to the gas cap is not completely closed, that the check engine light may come on. Perhaps it settles after a few days after going over a few bumps.

I have a 2001 Dodge Intrepid and my check engine light came on but I dont have a check coolant light does that mean I need to change my coolant?

The Check Engine Light has come on because the computer has detected a problem with the emissions system. It has nothing to do with the coolant. Take it to a trusted professional and he will scan the computer with an OBD2 scan tool. He will use the fault code as a guide to determine what the problem is. also if you had recently messed with the engine as in unplug something and turned the car on the the light will be on for a few days but eventully turn off

You have a 99 Chevy Malibu Ls the check engine light comes on for a couple of days and than it shuts off could this be something serious or what would cause this?

Whenever the check engine light comes on it means that your computer has detected an anomaly. Check the code to see what the computer has stored. Code scanners are not very expensive and can help you figure out how your car is doing. They are available at most DIY auto parts stores. =New Answer Headline= Definitely have it checked out. Mine would flash on and off and then not come back on for a few days or weeks. The next thing I knew, I needed to have a new engine because there was no oil left even though I kept up on service. My oil light didn't even come on to warn me!
