Got a 2.0L '94 Jetta GL, had the catalytic convert and oxygen sensors replaced to pass reinspection, but the CEL keeps flickering, without any apparent trouble codes from the car's computer, anyone have any ideas why the light is flickering?
I notice as I increase the engine's RPMs, the light flickers more dimly.

Re: CEL Flickers Consistently (Ls3)

a flickering check engine light...usually REALLY is telling you to CHECK THE ENGINE. lol....if the cel stays on without flashing .....its just the normal bs codes or twitch...
but if its flickering/flashing...i would check it out on vag,double check it ...look at everything.

well then go down the list and manually check every little thing...from your oil to your fuel filter to random sensors....
bottom line flickering cel light is one of two things....SOMETHING serious OR the bulb is going to blow out soon lol

Had so much planned for the Jetta, heh, have to get rid of this damned light[HR][/HR]​
lol like i said ...could be something serious or nothing...
just do various tests on your car...check all vital parts and sensors.....just make sure everything is running properly...

i used to get on again, off again (but not flashing or buzzing) CEL's on the vr cuz of the cam position sensor. after i replaced it everything was happy again.

Is it flickering like a random flickering? That might be a bad bulb or a bad ground for the light. My airbag light flickers because of a bad ground.
If it's a controlled, pre-programmed ltype of flicker - that probably means something.

It flickers too fast to notice, at times, and really gets dim when I work the engine up. But it doesn't seem to be blinking at a set rate.
