ok i havea86 gt5 speed i swapped and put the motor out of my 87. in it i reused the upper and lower intakes from the 86 tho. timing is set it cranks but my prob is when u give it gas it revs out at about 4500 and has no horses it also is really jumpy and has a lil popping kinda. if i dont figure this out im gonna go ahead and go to carb because this efi is driving me nutty
