still looking for answers

So here is a update and what is still happening. Had the CPS recall done truck is still acting up.Changed fuel filter and cleaned the bowl, changed the oil. Now I start my truck and it runs ok for a little while then when I am going down the road it either loses power or I get no throttle response, I have had it where it goes down to idle and you get nothing from the pedal. It seams that it gets worse when the truck warms up. This started happening all of the sudden. By the way my tach does not move when I am cranking it to start it. Anybody have a idea????

I'm thinking fuel pump or any oil leaks from the high pressure oil pump. I had a similar problem a ways back and it turned out to be lack of oil pressure due to leaky HPOP.

I looked at the hpop but did not notice any leaks. Somewhere special I should be looking for them? Also I was thinking maybe a bad cps right out of the box?

That is quite possible. Faulty parts sometimes make it through. There was a recall on the cps for the 2001 supertduy. The leak I had was very noticeable on the pump. Maybe a plugged air filter. Not sure what else. Just throwing out ideas.

a bad IDM would have those symptoms.

if you see a light at the end of the tunnel, it's probably just a photon torpedo

Filter is clean and I appreciate the ideas. This one has me scratching my head.

Have the truck scanned for codes. Most likely the shift lever will need to be replaced (wires shorting out) or the pedal assembly is going bad.

scan for codes with a PROFESSIONAL scanner, not some autozone junk.
Report back.

Also, a superduty's tach wont' move when starting. That is OBS.
