Ok so what do you think it could be be? i tried everything and nothing works. do you think unpluging the battery wont work? or do i need to go to something and have them clear the code and see if it comes back?

 

Autozone or someone can clear the code. If it comes back on there are some checks I may be able to provide.

 

I think your tune is off...

edit-nvm

i thought it was a lean code.

if its not switching its a mechanical problem i believe...

 

Ok i jsut got back from autozone. im about to go drive it around.. what are the things i need to check if it comes back on??

 

A check engine light lol

 

Yeah bro, you never had one of those? your car must have no mods done.

 

when i had this problem i checked that fuse then i bought a 02 cel eleminator off ebay and its didnt work so then i bought an acdelco sensor and got an angled o2 sensor cel eleminator i dont know what those two codes are but keep trying.

 

so did the gm 02 sensor fix youre problem

 

could try checking the wires that go to o2 sensor and check and see if they aren't freyed or cut, but thats probably unlikely. Have you gotten rid of your post-cat o2 sensor?
