any ideas?

Still having problems with loss of power under load (grades). In the last 2 months I have done the following: BTW..no codes.

changed mufflers and cat's (Flow-tech Raptor's)
TPS sensor
EGR sensor
tranny filter
fuel filter
cleaned throttle body
checked for vacuum leaks
tune-up - plugs, wires, cap, rotor, coil
cleaned injectors
air filter
and, probably something else I have forgotten. [img]images/graemlins/cussing.gif[/img]

Re: any ideas?

Have you done a compression check? Your cyclinder pressures should all be within 75% of each other. Loss of compression would explain loss of power on an incline.
Possible explainations for loss of compression are rings, valves, seats, or maybe even a cam lobe (which would make the vehicle run rough, so probably not your problem).
Question: Does your engine run a little rough, then smooth, then back to rough on occassion? If so, suspect needing a valve job.
