Default reduced engine power + knock sensor

Hey!

I get reduced engine power & TCS service after a mile or even sooner.. 2 days of testing, if i deactivate TCS car can be normaly driven.

Yesterday i took apart throttle body and cleaned it with brake cleaner, while i was at it, my oil pressure sensor is bugged, so i decided i should finally replace it. Took the long way and removed manifold off, cleaned replaced he sensor, bolted, connected everything, now i get knock sensor code + if i floor it car does NOT have so mutch power like it should and at low RPM it kinda delays in throttle, power, delays, power..

p0332
p0410
P1221 TP Sensors 1, 2 Performance
P1515 Command vs Actual Throttle Position Performance (PCM Module)
P1571 ASR Desired Torque

C1278 TCS Temporarily Inhibited By PCM

B2723 PASS-Key Detection Circuit

The codes you have are all over the place---Secondary air--Knock sensors--Traction control--throttle position--Almost sound like some pigtails were not plugged in -or reversed--If you did not have these codes before taking the manifold OFF it must be something you did during re-install to cause so many codes on such different issues
However the TCS and the throttle position codes do affect one another as the ECM uses the throttle position as part of the traction control---Your car is going into "limp mode" which is common for TCS and throttle codes
