Any suggestions on what to do next? I have replaced all the vaccuum lines, the MAF sensor, both relays, the connector, and the ECM. I have adjusted the TPS to .54 volts, and still the SES comes on intermittently and the car runs like crap. It may go off on it's own or if you shut it down. Sometimes it comes back on when you crank back up. BUT NO CODES!!!! Only 12(all clear) Is it time for the dynamite???

 

I'm not Vadar(damm..), he must know whats going on with your problem. You could always convert to Speed Density or somethin

Screw Dinamite!!! some of my buddies need a car to trash in their music video.... your could take out your aggression and your car would be famous!!!!

 

Have you checked all the wiring going to the MAF and the relays. This sounds like a good place to go next. Let me know if you need a trouble shooting guide. I'll try and type it up for you or send you a copy per US Mail. Email me if you need it. irocbsa@mindspring.com

Sounds like more of a computer related problem. I've heard the same problem before but couldn't find the post in the archives on it.

thanks for posting the link, i've been looking for that info but i guess i overlooked it...

 

I am assuming you unhooked the battery while replacing all those parts? If not, you may want to try that.....just a thought though
