I have posted on another thread but no replies. Issue: 04 f150 5.4 leader. I had an edge evo on it and put on K and N CAI. It wasn't matching up and ran sh#$y. Upgraded to Diablo trinity that has a program for the K and N but now I throw the PO147 lean bank 2. My long term fuel trims seem to be out of wack (I can watch them). Somtimes she runs fine and alot of times she stumbles on cold mornings and after reaching Coolant temp. of 190 (closed loop). I cant find any vacuum leaks and I have new O2, OEM coil packs, fuel filter that I will install tmrw. MAF is clean. Any ideas would sure help as I really don't think its fuel filter, O2 or coil packs as no other codes are popping. I did have a random misfire code with it as well but after clearing, it hasnt come back for a few day's. I also had magniflow installed at time of CAI but don't think that matters...........just giving all info. Please...............anyone?
