low rpm under power miss
Hi I'm new to the fourm. My truck is a 96 f350 it has dp tuner, open ehaust, and afe airbox. Other that that its tock. I started the truck this morning and it had white smoke till it was all most warmed up. The truck sounds to have a miss at idle, and when it goes into overdrive it makes a moaning/droaning sound that I can feel untill the rpm's and speed reach 45mph or above. I've used fuel system cleaner, checked the under valve cover harnes. It has ew oil and fuel filter also new ipr and ipc. The problem seems worse at times and other times it seems better. Not sure if injectors or idm could be the problem. Any help would be greatly appriciated.
