Re: changed the oil, and now a check engine?? (gmugolf)

Only thing that could be closely related would be if you bumped your PCV upper hose when removing the filter. IF you havent already had the PCV system extended warranty the canister or the upper hose may have taken a dump on you.

I recently got that replaced, but ill go look at the filter area, to see if there are any issues.

Get the code pulled from AutoZone for free.<p>Then look up the description of the code:<br><A HREF="http://s40concepts.net/forum/index.php?t=msg&th=10481&start=0&rid" TARGET="_blank">http://s40concepts.net/forum/i...0&rid</A>=

so I had the code pulled at a auto shop, and like 7 codes poped up. Now considering that my car is running great, the guy said, "the ecu is probably going a little crazy on you". so he cleared it, and said if it comes back, then you have a problem. It hasnt come back.... thankfully
