this afternoon i scanned my car 88 w/ mass air conversion it has a new(remanufactured) computer for a 89. It has been about a week w/ new computer and it still has some problem learning the idle so i checked it out and results:
KOEO:81,82,95
C :13,69,96,95
Run : 19,12,58,99
Looks like your car was a 4 cylinder car to me or computer and its tripping a ton of codes related to that. Some of those key on engine off codes are 2.3 related.
