[Ace 2.0]

well i was sitting at a redlight,the CEL came on and stayed on,the car ran fine,did not hesitate or sputter,she ran just as smooth and stable as normal.im not too worried about it,but it is just staying in my brain that it came on for no reason.my friend has a code reader but its late and i dont feel like finding him,hahaha

she has 78k on the ticker and run like she is brand new.i just wanted some suggestions from the experts.thanks alot>>>>>>>>>>>>>>A.J.

Could be alooooooooooooot of things. Only way to find out, is hooking it up.

I'm putting my chips on a cylinder missfire code.

Seriously... pull the codes and let us know - without that there's nothing we can tell you.

If it was a misfire, the CEL would have blinked, not just come on and stay on.

Pulling the codes will end the debate.

(A misfire code will be waiting for him when he does. )
