so a little backround, bought my stage 3, drove it straight home ran perfect, did some maintinence like timing belt, wp, gaskets and such, starts right up afterwords, runs great till i try to rev it, it falls on its face then stumbles and then idles itself out, pretty much thottle cut anytime it reaches non- vacuum, if i barely touch the throttle i can ease the rpms all the way up to 5k if i lay into it at all it stumbles and cuts out, i tried throttle body adaptaion- no help. codes i kept getting were:

VCDS Version: Release 11.11.2

Address 01: Engine Labels: 078-907-551-AZA.lbl
Control Module Part Number: 8D0 907 551 M
Component and/or Version: 2.7l V6/5VT G 0002
Software Coding: 06611
Work Shop Code: WSC 63251
VCID: 3469EBE504204E3
1 Fault Found:

16490 - Manifold / Barometric Pressure Sensor (G71) / (F96)
P0106 - 35-00 - Implausible Signal

Readiness: 0110 0101


and every once in a while i would get a:

16622 Manifold/Boost Sensor (G31) - Signal Too High
Intermittent

so i tried the obvious- replaced map sensor and absolutely no change, got a very good deal on a awe stage 3 fueling kit , swapped it in and no change. its to the point where i cant even start it to get it running, seems like it has progressively gotten worse over time untill where it is now

anyone else evey have issues with this code? i am at a total loss and it seems like this code never pops up

 

so a little update, got a set of new plugs, tried to get it running for about 30min, seemed like it was complelty flooding itself out, finally got it started and it will do the same thing...idle good but once throttle is given over 1/4way it will buck and do throttle cut, same codes appear for the g31 sensor

also followed ever part of the harness i could and found no rubbed through areas and no damaged areas that were visible

..ok this really doesnt help me, i already checked voltage, it has 5v on the supply line and around 1.95 on the signal line at idle. voltage doesnt change from 1.95 with key on or with the motor running at idle, voltage does change with change in throttle but doesnt seem steady
