Okay I have a 1996 f250 powerstroke 7.3 so far I've changed the trans filter fresh rotella T oil change today and a brand new GTP38 turbo (OEM) I'm sure
But it feels like it's low power no check engine light or whatnot all I have is a abs and brake light gotta line leaking but I checked my back pressure sensor and the gas return line and it's completely plugged with rust and soot I mean not even able to get speedo cable in there could that be it it doesn't feel or sound like a miss idles just fine but feel sluggish trying to accelerate on the highway has a TS 6 position chip but when I get on it hard the turbo or exhaust makes a fluttering noise it's not a clean constant pull of air please help don't want to spend a bunch of money on parts I don't need 205.000 miles

Re: HELP!!

My 97 has 205K miles on it too.
You are saying your exhaust back pressure sensor tube was plugged up? Remove that sucker from the vehicle and clean it out! You must get it clean for good performance this is the best place for you to start.

Why did you install a new turbo? and who did the work?
Were you chasing this same issue?
Did the up pipe gaskets get changed out also?

a little more history might help here, I assume you changed the turbo because you are chasing this issue? and now it is still there? Or is this a new issue since the turbo install?

Re: HELP!!

What is "gas return line".

Have you checked your fuel pressure at WOT? MAP sensor hose? Disconnect the electric plug on the MAP and see if that makes a difference.
