I have tried to search but found a lot of dead ends. I just got a aps st kit installed and when getting it tuned on the dyno after 4 pulls the lights came on and no trottle response now. I read on anouther post that this problem destroyed a utec which is what I have and hope this does not happen. This is the first and only time this has happend.

do u have the DTC number?... i left my Z sitting for about 3 weeks at one point and when i drove it the next time everything was fine but out of nowere the check engine, tcs, and slip came on. the car idleled perfectly but didnt have any throttle response. i have a code reader so i hooked it up and i got a code that was manufacturer specific but i looked it up online and it turns out it was something with the throttle. so what i did was disconnect the throttle and got me a electronic contact cleaner and some electric grease and cleaned it and pluged it back in reset the pcm and it was good to go.. u can reset it by disconnecting the battery for about 30 min in case u didnt know...good luck man let me know if it helped.

I don't rem the code but it was a etc code (electronic throttle control). how would this effect the utec? I just bought another one.

Well, mine went away after I replaced my CPS. That is the code I got.
However, you're throwing a different code. You said yours was:

P1122 Electronic Throttle Control Actuator

Sorry. Doesn't look to be the same problem.

The first tb was ruined so was the utec. Got a used 06 tb from a friend that worked fine with no utec and then got the new utec, a hour later the car will not rev with or wo the utec.he said it was giving a drivetrain code. He believes it is something to do with the traction control causing the issues and says he wants to disable it. Any tips on what to do next?

Well bought a new tb, and the same results. Revs with no utec but won't rev with utec. All the pins in the harness????

These are the 3 lights I have right now. throttle response feels mushy...lagging kind of like an automatic.

The car is @ forged performance now. I sure hope its something small when they find the problem. So far the shop that did the install couldn't fine the issue nor nissan. My fingers are crossed.

No news yet. I think they are trying to finish up another car before they start on mine again. I just hope it is something small. Can't wait to post the problem when I know what it is. I have had the wrost time with this. Should have left it stock.

The problem was that the engie harness was resting on the exhaust manifold. Forged replaced it now it works.
