i have a CEL and cant get it to go away or figure out what it is. i hooked up to OBD-II scanner at advanced auto n it didnt come up with any codes. now i cant get my inspection or emissions. any ideas of how to help?!?!?!?????

 

take it to a dealer they should be able to scan the code for you for free.

 

no code came up? see if someone local has a code reader. mine works perfectly in the cobalt and was 100 dollars. got it from sears hardware.

for a temp fix, try disconnecting the negative terminal on the battery. it should go away for a little while at least. test it out, see if it comes back. if it does come back, keep notes on how long it takes to come back. then if you have to do it in the lot as you pull up or something.

 

ive disconnected battery. normally comes back within 10 minutes max 15. i was told that the dealer would charge just to scan the code but i will call n ask tomorrow. i put up the price for the bumper d4u2sot

 

the dealer does it free, as long as u go with it being warranty thing, just go in, my check engine light is on, i dont know why, i did that they looked at it, said my old intake caused, it, they cleared it, and i was on my way, free of charge

ps-they do logg it, they get the paperwork and **** done, so it will go on record, best way it to know someone at the dealer so they can hook it up and look at it

 

well i know one guy that works at the place. i am going to call and ask him tomorrow if he has any idea and my car is still under warranty so hopefully its free

 

ya and even if the light is out the code is still stored in your ECM's memory so they can get it either way. its better if it's on when you go in though.

 

missin on a cylinder and runnin lean

 

try checkin ur spark plugs...take one out and see if the tops white/grayish color...i had same problem..try putting the stockers back on,or buy some zex plugs 1 step colder

 

i got stock ones on

 

P0171 and P0300 are my codes
