I need help???? I have a 89 coupe that i bought a while ago, well i took the the 93 lx motor i had (gt40) and threw it in my coupe??? heres the problem now the car runs like crap? I put the 93 computer in it helped a little but not enough to even take it out of the garage?? is there a difference in the wiring harnesses from 89-93????? could that be my problem? i also was told that the computer from the 93 due to it being an automatic and my coupe is a stick, that that wouldnt work either ,,,,please help im desperate????? please email me to [email protected] thanks
