Artemis Posted January 21, 2009 Report Posted January 21, 2009 Thats right, took the car in to get scanned today. Hard to find a place around here where they'll scan my OBD 1.5. Anyways, first time I've ever scanned the car and I got 17 codes... although it fluctuated from 17 down to 13 and back up. Mechanic and I agreed it may just be my ECM. Any thoughts? Car was pulsating at idle, we cleaned the IAC and now it idles fine. Quote
slick Posted January 21, 2009 Report Posted January 21, 2009 Are you 100% positive that the ECM wasn't hooked up to power on the bench, and somehow codes were obtained from there, since there were 0 sensors connected???!!! LOL Yeah, I'd gonna go out on a 5' diameter branch here and say bad computer. Quote
1990lumina Posted January 21, 2009 Report Posted January 21, 2009 Could be a poor ground or something to the ECM as well... Quote

Artemis Posted January 21, 2009 Author Report Posted January 21, 2009 I can swap an ECM from any 95 LQ1 W-body right? Quote
