THANKS

does anything happen differently when the light comes on? or does it just pop up w/o warning?

 

If it goes away, then it probably isn't a major problem. It sees an error, the light comes on, then after a certain number of cycles, if it doesn't detect the error again, it resets itself. Maybe a misfire or something along those lines.

Not sure where you are located, but I can scan it for you if you want.

 

yeah where are you at? i have an OBDII scanner if you're close

 

i live in clearwater, but if one of you guys can gelp out ill meet you wherever. and yes it comes and goes, but no difference in driving thats why i dont understand. thanks for your help guys

 

That's far as hell from me, maybe one of those Pinellas guys can help you out.

However, if you feel like driving quite a bit, I can help you. I have full vag-com, so we could check certain measuring blocks as well as read codes.

 

well if no one else can help me out, then i guess ill plan a lil trip. thanks for all your help BisquitMan. do you go to any meets i might be able to meet you at?

 

Nope.

 

vag-com. can u scan obd1 with it? ive got a cel come on when at WOT 3rd and up. but then goes off.

 

its probably your O2 sensor.

mine did that as well. but i got a new o2 sensor and all is good.
