hmm having similar problems to this guy though mine will I can hear backfiring under the hood if I stomp the gas while trying to start it. only had it happen twice but was after sitting for a couple days. finally started real rough and just had to keep giving it gas lightly til it smoothed out. it does idle rough but that I am pretty sure is my ignition wires which I am changing out today. Been getting jerking too on hills too but no codes were coming up. guess I will try the wires and plugs then the crank and camshaft sensors and if all else fails a 2x4 lol I refuse to take it into a mechanics only to get bent over the counter. Reading this thread would I be better off trying out the MAP sensor before the crank and camshaft sensors? My fuel pump is fine and have plenty of fuel pressure. Also it seems worse when its cold out.
hmm ok did just get a 21,41,51
