My daily driver is a 01 eldorado with the northstar engine. today i installed new fuel injectors ,fuel pressure regulator,new intake gaskets., and while i was at it i installed a starter as well. it went back together pretty easy but when i started it ran very rough,stumbling. it stays running, but like i said it idles very very rough. i double checked all my connections,it did set a code p308 cylinder 8 misfire. I almost seems like the map sensor or maf sensor isn't connected but they are. could it be the wrong injectors? i checked the part #'s and they were identical to the old ones. i am lost here. any help would be appreciated.
swapped back the old injectors and the car runs great. Bought these injectors for $90 on ebay, i guess you get what you pay for. i was suspicious when the boxes weren't GM. ordered a new set from rock auto.
