Hesitation - What is the Cause?

[DucksnDiesel]

My DMAX has started having severe hesitation when I step on the pedal. It will start going, bog down for a second or two, then begin to accelerate. This has been going on for several weeks and I have refueled several times. I buy fuel at the same station every time and they do a good volume so I do not think it is bad fuel. The fuel filter was changed about 1,000 miles ago. I checked the air box and air filter - they were clean/clear. Any suggestions on what may be causing this? Thanks.

That sounds familiar Ducks - the techs tell me it is an 0093 code (I think??) which is a "large fuel leak" according to GM. My truck has never leaked fuel at any point - my biggest fear is that I'm going to have to change out my pump now that I am off warranty!!!! :mad: Let me know if you find the culprit!!!
