I tried to search the forum, but since the changes about a week ago, now I just get a blank page that says loading and never returns any results. A google search found this thread for me which seems to match my symptoms a lot closer.

Truck would intermittently go into some kind of low power mode, in fact the more I stepped on the accelerator the worse it got, letting up on the pedal and it would start to gain a little power and shift again up into next gear, would never go over 40 mph while doing this.
No CEL
No codes at all to the OBD2
Turning the truck off and back on clears the condition and happy motoring until it happens again. this happened about 4 times within a month. I think it was always in the afternoons, in the thread above I read about warm fuel being returned but I don't think that's going to be my problem because I live in SoCal and it's pretty mild here, plus I have a fairly short commute, only about 10 miles.
So I was thinking after reading that thread and others that the previous owner may have had a custom tune that was misbehaving and I had the dealership reflash the ECM to stock.
Within two days the problem came back only now with new symptoms.
the CEL light came on, and stayed on.
turning the truck off and back on did NOT reset the situation anymore
The code P0087 was picked up on OBD2 (which is how I found the thread linked above)
Took the truck back to the dealer armed finally with some real data on what the truck is doing.
Dealer tells me the wiring has been spliced and looks like the previous owner had some kind of mods put in place.
but back to the subject of the thread, they are saying they are getting a 2nd code, and that the EGR solenoid is bad, and that's going to run $700
When I searched on EGR solenoid symptoms none of that seems to really match. Even when I was having the problem, it wasn't rough idle, there was no pinging, and the truck never stalled. Poor acceleration is the only thing that matches.
Would EGR solenoid create this condition? Would it be intermittent before a ECM reflash and then very constant afterwards?
Dealer also says now the P0087 code is cleared and that it's back to driving perfectly normal. (I did have one full good day between the ECM reflash and the problem coming back and staying on)
any suggestions? again I apologize if this is covered in depth somewhere, I don't know why search seems to give me no results at all.
