I got a good one. My 5.0 transplant in my 98 explorer sport wont start. I can get it to start every once in a while, but when it does start it runs really rough at idle and when you give it any throttle it starts spuddering and backfires. Sometimes when I try starting it, it will backfire. This is what happened, I was at a stop light and the rpms dropped and it started running like crap. It would barley move and it was chugging and backfiring. I keep getting p0353 and p0354 codes. I've replaced the coils, plugs, airidlecontrol, intake gaskets both upper and lower. Also this engine only has 4000 miles on it, oh and I readjusted the valves. I have roller rockers on it. If any buddy has any suggestions im open for anything.
