Low Power when pedal is past 1/4

Hey All, I've seen this issue on other treads, but I have never seen anyone finish the thread when they figure out what is wrong.
Any way I have a 96 5 speed, and it runs really well as long as you don't push the go pedal to far. If you go to far it falls on it's face. I have cleaned the EBS line, changed map sensor, but still the same problem. It's not a big deal until I hook onto a big trailer and pull a hill. Does any one have a clue what this could be? Help would be much appreciated.

What does it do when you run the pedal through its travel with no load (parked in the driveway)?

I had this problem on my 03. I blew the 20 amp fuse for eng mgnt, right below it was a 20 listed in the manual for eng mgnt(gas only) so I pulled it and used it. Truck started but barely climbed out of my driveway, felt like the tranny was slipping. Had 1/4 throttle only felt like limp mode, backfired and missed in park if I stuffed it quick.Took for ever to get to 55mph, just like when you unprogram your truck. Went and picked up a new fuse, drives perfect. Hope this helps.

I've seen it where guys don't have anything past half pedal and it ended up being the icp sensor, but I think it usually pops a code. Are you pulling any codes? Just an idea or something to look at

I haven't pulled any codes yet. I've been busy, and out of town a lot, and it runs good as long as you don't get carried away with the pedal. I am going to find someone to scan it when I get a chance. It does have the problem in the driveway without a load or with. Thank's for the reply.

Hey all, I wanted to give an update on this problem in case any one else is, or in the future has this problem. I found that the screen on in the Fuel pressure regulator on the side of the fuel bowl was totally plugged. Runs great now. Have 4" exhaust and chip comming, can't wait!
