just swapped a 93 explorer 4.0 into my 91, the 93 has 65k miles on it, i only got half the exhaust hooked up and i think it is my problem but, wen im goin down the road it has minor backfires and it cuts out especialy going down the highway in 3-5 gear i think thats the exhaust but not sure, everyone i talked to said timing was off but its efi so it dont have a carb to change the timing, its all electrical right? how do i fix this?
