more code ???s
ok so i figured out my 89 had a bad computer, got a reman unit, hooked it up and let it run a little bit, then run more code tests.. results as follows
21 - ECT out of self test range - FIXED by taking out the brand new one and putting the old one back in
44 - Thermactor Air Injection system inoperative (Right side)
31 - PFE or EVP circuit below minimum voltage of 0.24 volts
13 - Cannot control RPM during ER Self-Test low RPM check.
all these were with engine running, other than a 77 which is me not doing WOT, my fault there....
big ones to me are what the heck does the 44 mean, and what exactly is the PFE/EVP???
could those 2 cause the code 13?
also KOEO and CM only gave me a 31 on each
Thanks again
