You are the best!!
Today, with your dokumentation, I was able to start the motor. Now I only have the little issue, that the motor is turning up to the limiter without touching the throttle.
But it runs! I'm so happy right now! And this "little issue" should be solvable in the near future. At least I hope so.
Maybe you have any idea, what the reason could be? I already disconnected the TPS, but there is no change.
Thank you man!
chrispoe:
The TPS won't do that. It's only purpose is to see if the throttle plate is closed to enable the idle valve or WOT run the engine in closed loop mode.
If the engine is revving up without pressing the accelerator pedal, that means air is getting by the throttle body. I would first disconnect the throttle cable and verify the throttle plate is fully closing.

Ok so tomorrow I will take a look at the throttle, wheter it's open or not. And if the throttle is ok, then I have to look for an other spot, where the air could get into the motor.
chrispoe:
The engine speed is controlled by the amount of air entering the engine. There should only be four ways for this to occur, the throttle plate, the idle speed adjustment on the top of the throttle body, the idle valve, and cold idle bypass valve. When the engine is cold, it should idle around 1500 RPM and slowly drop to about 850 when warm.
Few questions, when you changed the plugs for the TPS, VAF, and ECU, did you splice the wiring or did you pull the pins from the original plugs and put them in the new ones.
Did you wire up the variable intake solenoid? If you didn't yet, I would use the Blue/Orange wire that went to the Barometric sensor(no longer used) and just extend it to the solenoid plug and connect the wire to C205-pin S. It activates around 5000 RPM and adds an extra 5 HP.
