OK, I never had a question before becuase this is a pretty thorough forum for helping the average joe, but I now have a good one for you all...
My X: '00 X, 2wd, 4.0L OHV, Auto
Situation Precurser: Did tune-up on my X a month ago, I knocked a hose off from the DPFE (nearer to firewall) and noticed it right when I turned the truck on. Ok, put the hose back on...no problem. Truck ran fine until yesterday.
The Situation: I was driving up a grade, heard the notorius "Hiss" and knew right away it must be that same tube. Pull off the freeway, pop hood, Yep! its the same tube, now completely missing, fell off somewhere on the 101 grade in Camarillo. Ok, so I get up the grade (probably the killer) and get to the nearest Auto Parts store, PAW. (Six mile drive, ugh) I Put on a new High-temp vacuum tube with clamps. Start truck, its certainly not hissing and it is running slightly better, but still not completely normal. Make it back home and the shifting is wacky, sluggish, rubberbanding acceleration or little acceleration in all, little power going up hills, and that ever telling sound of 'ticking' upon pressing the gas. Maybe the cat? (although still moving slightly and not as bad as without the vacuum line ot the DPFE)
The DPFE is a part of the EGR system, I've heard of the blow-torch effect and have little evidence of it. What I mean is that the only thing affected by this blowtorch was the wire-spline only (no wires luckily) and luckily NOT the intake manifold as I've heard so much about. whew!
My Question: do you think the EGR valve is stuck open due to the roadside issue I had? Or is the problem somewhere else.
Other infomation: I had a friend, who owns a shop, code out the ECU, I get codes: P0171, P0174. He cant make $ if he's working on my truck for free and I'm already a starving student who can't afford this failure. Argh.
here are pics:
The Hose which was replaced...
The Blowtorch effect, (*Note that there isn't any intake manifold damage)
The Code manual, the codes and common factors:
