Hello. I have a 2004 LLY with 6000 miles it has developed a low speed surge with the brake applied. It only happens with the engine at idle speed and the brake applied but the truck still moving. Has anyone else experienced this or herd of TSB ?


Thanks AL

I don't really have any suggestions or help, but that problem started
on mine after I had the reflash. It also surges now at 35mph with
the throttle lightly applied(like when driving on side streets).
I haven't talked to the dealer yet though.

I have noticed the same as Ccolmar. I had mine reflased for the "parking lot surge" but now I have surging in the 1000-1200 rpm range versus 800-1000 rpm and it usually happens when I am rolling around 10-30 mph depending on which gear I am in to be around the 1000-1200 rpm range. I have also not said anything to the dealer yet...

Same as all of the above with the latest reflash. Solved some probs and discovered others, it seems. Did any of you notice a very small drop in performance, as in acceleration? Mine seems a bit sluggish now after the reflash.
