I was crusing down the highway with the cruise set at about 72MPH. I had just restarted my trip after stopping the truck for lunch break - I had been driving for about 4 hours prior to stopping. I let the truck idle for about 5 minutes to let the turbo cool off before shutting it down.
Once I re-entered the highway and set the cruise, the truck "bucked" about 5 times. I tapped the brake to turn of the cruise - the truck was still running fine. I do not believe the RPM's dipped when it was bucking, but I can't be certain as it happened so quickly. It was fairly violent and the "bucking" happened in very quick succession. Anyhow, it has not done it again and I've driven over 200+ miles since the "bucking" happened - any ideas?
Thanks!
