I love my 02 super duty powerstroke. It sees very little use as I really only use it in summer for camper hauling duty. I've owned it about 5 years or so and ever since day one it had had this issue that I have not been able to solve. Googling isn't much help other than it seems like others have had the same thing.
The problem is a surging/cutting out just off idle.
It idles great, and as long as I am accelerating it runs and pulls great. Going down the highway and steady on the throttle runs great. Cruise control runs great.
But every time I have to go slow on a rough road (barely above idle slow - just touching the pedal) it goes, then rpm drops, returns, drops returns. So holding pedal down about 1/8 to 1/4 inch the throttle cycles off/on/off/on...rinse repeat. But I can accelerate through that spot with no problem.
Pedal assembly with TPS and IVS are brand new Motormaster from the dealer about 3 years ago to the tune of $1000 and resulted in no change at all.
I have autoenginuity with the Ford pack but don't see anything on there that points me to a solution. Anyone else experienced this and found a solution?
I love the truck and it serves me well but I hate the way it drives when going slow
