I have a 1995 Intrepid that has been doing the same thing. My brother, who is a mechanic, told me that it is most likely a faulty oxygen sensor. He said that there's no urgency to get it fixed because it doesn't affect how the car runs. My check engine light has been popping off and on for several months and I haven't noticed any change in the performance of my car. For me it was two oxygen sensors (out of four). I was told that some cars do not start when the sensors go; therefore, I did not want to take a chance, so I ended up replacing them (I did get a deal:the sensors were $75 each; and a friend mechanic put them in for free). Oxygen sensors do affect the performane of the car. The o2 sensors get to better gas mileage by allowing the correct fuel/air ratio I have a 99 Intrepid and the repair guy at the dealership said that the check engine light will come on, but after the car is turned off and on a few times the computer resets itself and it will go out. The check engine light comes on for a lot of different reasons, mine was idle was low (due to a leak in the lower intake gasket). Hope this was helpful
When the check engine light comes on it should post a code. Use a code reader to see what the code is and ask again.
why do check engine light comes on
Remove the battery cables for 5 minutes, should do it. Then the computer will reset and relearn after driving again. If a major fault was present before, it will return via the check engine light. If you need an inspection, then unhooking the battery for 5 minutes and driving maybe 20-40 miles and then going for inspection may do the trick. There is a small window where the check engine light hasn't come on yet and the IM monitors are mostly ready for inspection.....just before the check engine light comes on again. It will pass, in this window. But when the check engine light comes on again, it will not pass.
The check engine light only comes on if there's a problem with suction (i.e. you filled the gas tank with the car running or left the gas cap open and drove. You can't reset it, you have to unhook the battery. If it comes on again, unhook the battery again. If it comes on a 3rd time, I'd see the dealer.
A rotax engine works on smoke, when the smoke comes out it doesnt work anymore!
No, the check engine light comes on when the computer detects a malfunction and sets a code.No, the check engine light comes on when the computer detects a malfunction and sets a code.
Check your O2 filters
The check engine light comes on at start up for a bulb check. If it stays on with the engine running the computer has detected a malfunction. You need to have it checked for codes.
Check the engine oil, sometimes when the oil is low the check engine light comes on while sitting still and goes out when you accelarate.

You can buy the check engine computer and the book comes with it. I know, I bought one. When your check engine light comes on, you plug it in and check the engine and it will give you the code and you look in the book for that code and it gives you the answer.
A low battery can cause the electrical system to flash check engine lights
