throttle sticking

My father has a 2008 6.4 with just under 40K. He says the other day that while rolling through a parking lot the engine began racing without his foot on the pedal. He was able to stop and shut the engine off. When he started it again, it was fine. Anyone else experience this??

You mean 6.4 not 6.7, the 6.7 wasn't offered until 2011. I don't know much about the 6.4/6.7, I'm a 6.0 guy but I just saw this and thought I would clarify that. Hopefully someone will come along and help you out.

Heres a free

Thread revival. This just happened to me. Coasting off the interstate on the offramp the truck floored itself and went almost to 4,000 rpm. Stood on the brake to avoid smashing anyone and shifted to neutral. Hit reverse but I was almost stopped at that point. Made a bang noise but everything tranny wise seems to be fine.

I was not touching pedal, pedal was not stuck on floor mat. Just went nuts on its own.

Scary as heck

Any thoughts?

Drove it since? Checked your oil level to make sure it isn't full of fuel?

Ya drove it about 600 miles since. Oil has not fuel from what I can tell.

I believe it sucked in some oil hanging out in the intercooler and piping. The oil is a little over full but thats from me. It was only a quart though. Always just dump 4 gallons of T6 in it instead of measuring out 15 qts. Have been doing it this way for the last 38,000 miles.

I just put on my mishimoto intercooler and cold side pipe and found a good bit of oil in the old cold side pipe. I will be rigging up a CCV delete here soon to keep oil out of my nice new intercooler.

A little extra oil over that many miles and the blow by of a 6.4 might have been it. I will keep a closer eye on stuff and see.

Probably should start your own thread since this one is in the wrong section... Or get it moved to the right spot.
