So, I was leaving Lowes and was stopped at a traffic light. After sitting there for about 30 seconds my truck felt like it was about to stall. Lasted all of 3-4 seconds, but felt like the RPMs drop to almost a stall. The truck then idled up normally and hasn't repeated since. Air bubble? Fuel loss? too much flow?

any ideas? or...should I have searched first?

 

Hmmm, haven't heard of that at all!! I'll ask my buddy who's a diesel tech at the local dealership.

 

Software hiccup is my guess. I have the high idle doohickey hooked up and when I turn it on the engine sputters/stalls a bit. Sounds like what you describe.

Why it happened I don't know, just sounds familiar.
