Ok I am about to change out the actual PTU tomorrow, but today I had stupid high 3200 RPM so I took a log of it and will have it on the bottom of the thread. Also I noticed the PTU plug was badly damaged and if you touched it, it would change the idle and random misfire. So i wired in a new pigtail, and now its ALWAYS running in a LIMP mode (no throttle response, and TONS of misfire / popping). As of now the car idles at 1k but in limp mode. It really isnt road worthly anymore until this is addressed. Look at the pictures, videos, and my log



Here is my Throttle cable mess, and I dont know anymore ways to modify and make this work more flush.

anyone? I just swapped out the PTU and no change. Its just in a constant limp mode, and has a super hard time getting a steady idle. it will jump around and almost die a few times, then smooth out to a perfect idle (but in limp mode)
 
First off are you sure you have no boost leaks especially at the intake manifold. For some reason it seems like you are not capturing the IAT nor the MAP sensor so it is not logging. If the PTU is having issues then it won't fire on all 4. Make sure all holes are firing.
 
Oh I honestly didnt open up my values. I can do a better log in the morning. I went through the wiring, the vac lines, everything fricken possible. almost every Tbolt clamp was loose, so I went through and tighten everything down and replaced the ones that were strippedm ect/ I almost positive I have crazy boost leaks, but then again I was at least able to drive the car with the busted up ptu plug, but now it has a solid one, and a new ptu, and now she just is sitting. I drove the car around the block, and it didnt want to accelerate, but you could hear the turbo whistling away, and the bov but no get up. also, it wasnt bogging down or jumping around like misfiring, it just literally had no response. Its hard to explain to be completely honest


When the car had the high idle, while driving you could hear the BOV fluttering like it was looseing its boost just driving, not letting off the throttle. Its brand new extremepsi gaskets and rings. Weird

No cel codes!!!!!!!!!!!!!!!!!!!!!!

Just found out that the #3&2 are not firing, so I installed my COP setup, and still SAME issue. I tried to mess with the wires while it was running, and no effect at all. Im so stumped on this. Im going to pull the ECU now and check that
 
Heres a new log. My car is reading alot different then what link is reading. Im so lost on whats going on with my car

still needing advice please
