Can you be more specific? My guess would be your TPS (throttle position sensor).

It's like when I'm driving I nead to hold on brakes because van wants to go faster me not even touching gas pedal. Same thing if I turn of the car and start it back it acceleratetes by itself. Ramps up to high rpm. I was thinking something with gas pedal like wire getting stock not letting it go back.

i am not sure if that yr has a wired (no throttle cable) gas petal or not, if it does that electronic petal can be the problem as well as or the TBS...get it towed in to a chev gmc dealer....

Went to a mechanic to get it diagnosed it was fine on the way there, computer didn't see nothing wrong with it, they test drive it and it didn't act up. So they didn't charge me as they didn't find the problem. But I want to look at it my self. And just to be safe I had my driver switched to another truck for new.

I'm still going with the TPS. I had the same problem and it was intermittent and seemed to occur when it was damp or raining. I highly recommend all vanners get a ScanGauge. This device is a basic diagnostic tool and will read fault codes and reset the "check engine light". It also monitors all kinds of stuff that I don't know WTF it's telling me. But I do know what TPS is and that any value above zero, when my foot is not on the footfeed, is not good.

ScanGauge - Trip Computer + Digitial Gauges + ScanTools Better than a wheelchock, but also more expensive. I've got the original ScanGauge, which is almost twice as tall as the new ones. I have it mounted with Velcro™ on my dash. The new ones are way more cool and trimmer.
