I have a 1999 Pontiac Sunfire, 2.2L i4, automatic trans, no, A/c with 104,593 Km.
Do I need to have the ECM relearned even if I have had the unit reflashed to my specific Vin #?
I bought an ECM that was reflashed for my Vin # and when I installed it, it ran but threw up tranny codes, no tach, battery light on, and stall out in drive. I was told I need the car relearned as well. Does this sound right?
