H1 revs high while driving

Post by Jbswitches » Fri 07 Feb , 2014 10:06 am

My 6.5 turbo while drivin today started to rev way up then shut off. I pulled over and it started back up and while at idle it starts revving up high then down and after a few times it shuts off. What could be my problem thanks for any help. Jarred

Take a look at the articles on the flashoffroad tech page under diesel.

Off the top of my head it could be the throttle sensor at the gas pedal.

I always start with:
1. any codes?
2. any work done on the truck lately?
3. do you have a extra PMD to try?
