Idle Problem

[eikki]

Hello
My car won't idle. I must hold the gas pedal then everything is fine. If i let off then it dies.

motor b18c6, CR 8.9, 750cc injectors, sc6152sp turbo
gm 3 bar

I don't understand what would be the problem.

Try turning down your overall fuel trim.
move the iac duty cycle to just above "normal".

Now tried original MAP sensor and everything works. So there is the problem.

What settungs must i use for GM 3 bar sensor?

The motec sensor should be a good start. Check the wiring as well on the 3 bar.
