[QUOTE="Mark McAwesome, post: 1832126, member: 39107"] VICTORY!!!!! Everything is back together, cleared the ECU, cleared the TCM, warmed the truck up, prayed and then did a hard pull. No issues, truck pulled hard. Culprit: MAF Sensor on the firewall side of the the intake manifold. It hasn’t been looked at in 75k, it was covered in oil…dripping, never even thought to look at it. I’ll be checking and cleaning all three of them every oil change. Thank you to everyone for your input and advice, it helped me think through the problem and fix it. I’ll be taking out the 1050cc injectors next weekend, switching back to gas and having Ford do the PCM update for TSB# 20-2423. [/QUOTE]
