need some veteran advice

[rivercat]

I am having a WOT surge and a heavy lope at start up. If I let it sit a day and crank it it fires fine but lopes bad like shaking the truck funny car bad for like 10 secs and then quits. Also at WOT it surges tach sort of dies not all the way like dead needle but it sinks and comes back say dying for 3 secs then back for 10 then surge for 3 then back as long as you hold it to the floor at high speed. In the rain it surges even at low speeds and throttle or dies even at an idle. I suspect IDM but have no clue on how to change it or where its at on the left fender. I do some wrenching but dont like to especially in the 90* heat so a heads up thread with pics would be nice if anyone knew where to locate one. Is there any way it could be HPOP related or fuel pump going bad? Dont want to starve the injectors and eat them $$$. Thanks in advance for all that post. Im a Cummins expert, new to fords. have any 98-02 cummins ISB ?s fire them at me.

It was a sarcastic remark, I expected a better response then this, I guess people that are helpful either dont exist here or cruise the forums for newer generation engines.
