hey all this is my first post so I hope someone out there would be able to point me in the right direction to diagnose my fault in my XR-T I have an 04 mk11 and sometimes (oddly on the weekends) it will have a sudden loss in power and makes acceleration and taking off difficult, especially being manual. Iv pulled off my crossovers and checked to make sure that the throttle butterfly was operating when the accelerator pedel is depressed in different position. Found all to be okay, so I put it all together and took her for a spin under all coditions again and no matter where the throttle was it jus had NOTHING. so I kicked the throttle pedal in frustration and the proper throttle returned momentarily. I tried boosting it and it had no boost at all (felt like a laggy N/A) .. I parked the car in frustration again and I kicked the throttle pedal in neutral flat to the floor and strait back off and it reved to 2300ish RPM when the revs settled I did it again and it only went to 1100RPm... sometimes after driving for an extended period of time it will all return to normal and everything is okay. through the week.. drives well (aside from crap economy 300km to a full tank) and she idles fine. no shuuders, knocks, noises, misfires nothin. so I think that sums it all up.. im leaning towards my TPS on its way out? yet to test it or my actuator is sticking? once again yet to test it. checked for boost leaks, manifold leaks, (all vacuum leaks) cleaned the boost solonoid, throttle body is SPOTLESS, umm.. im still yet to get it tuned or speak to a tuner (ill go see spirrow) but just want to do my own diagnosis work before I go start spending hard earned cash on things that wont help me. iv also plugged a scanner on it to see what fault codes come up and after this issue it has an overboosting code in it. appreciate any help. thanks all! jared.

Hello everyone. Trying to troubleshoot a problem with my Turbo that about has me ready to burn the thing. Any application of throttle more than a half pedal and I loose all power and the ETC light comes on. If I slow to a stop the car idles surging with no throttle. Key off and on and you're good to go. I've replaced the throttle body to no avail, should I replace the pedal? Cheers.
