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".

report back

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