Ok guys before i get flamed for talkin about a non mustang related car let me just say thanks because id do the same but watha heck.! I just bought this 92 paseo (gas saver) for $400 bucks... i will post piks later.

Problem- does not pass cali smog. No C/I light ever (but does work as it lights up before i turn car on) previous owner gave me a print out of the smog that didnt pass so if there is a way you guys can help me diagnose my problem with it, it would great. I was told by a mechanic that saw this car say that the catalytic converter was bad..? Previous owner says he was told it was his egr when he did the failed smog.? I just dont wanna throw money away on such a cheap car but wouldnt the egr valve make the C/I light turn on..? I know that this car is too old and the C/I light does not turn on when cats are bad. HELP ME

 

There may be some inactive codes stored in the ECM. Perhaps you can take it to a parts store and have the codes pulled, maybe help narrow it down some? At this point it really could be anything.

 

dang.., guess im going to become a member of toyotanation.com just for the 1 question.

 

It may not have hard codes stored but it may have event codes stored. It could help. Or join toyotanation...There isn't enough information here for anything more than a guess. If you believe the mechanic you saw, change the cat and see if it fixes it. Do you have a copy of the smog report? Don't mean to sound nasty here but there isn't enough info in your op.

 

Sorry about the not enough info! Yes i do have the print out from the smog shop. I thought i would ask because i know that the print out of the smog can help diagnose or help finding the issue. Just let me know what numbers are needed to help out if possible. Thanks!
