I have a 98 Z24 cavalier and ran into this problem. I had in diagnosed and was told it was a #2 oxygen sensor located underneath towards the rear on exhaust pipe. Be sure if you do this yourself to disconnect the negative on the battery before you start. I wasn't told this and my car sputtered 3x worse than in was and had to do the whole procedure over again and then some just to get it to run half ways normal again!
Sensor Problem.
What's wrong with my 2003 Chevy Cavalier if the check engine lights on and a friends computer said "misfire cylinder 4 "? It studders also. thanks Dawn
If the check engine light is on in a 1997 Cavalier, there can be many different things wrong besides the EGR Valve. There could be bad oxygen sensors, low oil pressure, or even low spark.
Either your front, side repeater or rear turn light is blown, or the rear light is the wrong wattage or is a double fillament lamp fitted the wrong way round.
warning lights on dash mean something is wrong u would have a generator light a temp , and an oil light
Possibly. The check engin light (aka idiot light) is a 'catchall' indicator that something is wrong in the engine compartment, especially since the tranny is hooked up to the engine.
No....The engine mounts are in the wrong place.
You Probley have a blowed head gasket.
oxygen senser
Check engine light could be anything. usually related to emissions system failure of some kind. lots of auto stores will let you use there tool that will plug into your cars diagnostics and will give a code for what is wrong
Incorrect ignition timing or damaged valves would make a 95 Honda Odyssey sputter and backfire. Backfires are directly caused when ignition occurs at the wrong time.
If the check engine light is flashing, it has "stored a code" meaning that you should be able to read a diagnostic code to find out what's wrong, that way neither of us will need to guess.
