DESCRIBE ISSUE....just picked up project, wouldn't run, found melted injector wiring and replaced with new harness but also needed new (used from yard) PCM. Runs great but even though the CEL is off, the scan shows that it is on but with no codes. First time I scanned after repairs it did show P0700 and P0720. I plan to throw an output speed sensor in it after checking for debris on old one, but before I do that, any chance the yard PCM needs pinion factor procedure?
i would do it also i would relearn the CVI values
