Ok about a month ago my dad bought a 91 Sunbird 3.1 auto. The car has low oil pressure, and now it sputters and stalls. Sometimes it re starts, sometimes not. We think its a fuel issue. We just recently purchased a 95 or 96 Pontiac grand Am 3100 auto. The owner told us it has an electrical issue, we're thinking maybe the computer. If we go to a junkyard what computer would be compatible? Monte Carlo, Grand Prix, Lumina, Grand Am, Skylark? Would any 3100 computer work? Would the one out of the 91 sunbird work? Im assuming the 3100 is obd 2?
If I remember correctly you have to change the oxygen sensor and temp sensor like 3 wire to 2 wires I think? What else would be involved to swap the 3100 (95+) into the 91 3.1 ? Thanks in advance
ok thanks, car is a 95. Just mainly want to get it running, Hopefully the computer is fried and its not a short in the wiring harness somewhere
