hesitation/stumble

[WCrovo]

I was in LA last weekend and twice when accel from stop my truck hesitated. It was a quick stumble and it reved thru it. I wasn't towing and didn't seem to happen again. Any ideas? I hate to take it to dealer to have them waste my time. Any info would be appreciated. I quess it could of been bad diesel fuel.

I am having the same issue. I don't have alot to offer other than I had access to a scan tool this weekend and P0122 was stored. Appearantly this is "throttle position sensor low voltage" . This also caused my CE light to come on. Scan tool also noted that unit was "okay to drive" for what that is worth.

WCrovo, I hate to be the one that blames every stumble at fuel pressure, but it a good source to check. The lift pumps don't just suddenly die, they go out real slow. See if you can get DC to check you FP at idle and under throttle (while moving !!!). I'll wager a guess that your fuel pressure is very low under a load. Of course, may just be a bad load of fuel, like you stated.
