I ran out to grab lunch at work, stopped and filled up with diesel too. i left the station and truck was running fine. I drove maybe a mile, and pulled out of an intersection and when accellerating up to about 40 or so, the truck lurched at the 4th gear shift. caught me totally by surprise so i had no idea.
it continued to do this intermitiently for about 1/2 a mile. what i did learn was that my rail psi gauge was dropping to 0 when this happened. I was able to watch my rail psi as i was coasting down a small hill- foot off the accelerator, it was holding steady at 5-6k. it randomly drops to 0 and then bounces around for a few seconds. it would do this about every 2-3 seconds for roughly 1/2-3/4 mile and then poof gone.
I drove the other ~5 miles back to work, taking it easy, without issue. I was really easy on the truck, but did push rail pressure up to 20k once and no issues.
Any ideas where to start looking?
Truck has dual cp3s- orginal in valley with a new reg. 2nd cp3 and reg all new in fall of 2012- maybe 10k miles since then
Air dog 200 is running.
and i am 100% certain i filled up with diesel.
