96 T100 swapped to 97ecm for 1st gen s/c. Now have code p0450. Any way to trick ecm?
Hey fella's i have a 96 T100 that i am going to be installing a 1st gen(grey) s/c on the 3.4 have done some diggin n found that my
96ecm wont work, have swapped in a 97ecm , runs the same as norm but throws code p0450 (evap). I'm guessing the ecm dont realize my truck is not equipped with that system. Anyone run into this? Or have a trick to fool the ecm into thinking i do?
