Re: How to fix high idle with EFI ???

Originally posted by hobieboy
I have been chasing this problem since I went EFI

I'm using a Carrera intake with my EFI and I just can't get idle to drop below 1400 RPM. Worst yet, my idle speed seems to go up when ambient temp is high (>85F) AND engine is warm - it will go up to 1800RPM

I'm not using any idle control and my idle adjustment / butterfly screw is already completely off. I have tried to spray brake cleaner/propane everywhere around the intake, injectors, TB and even the air filter - idle speed doesn't change at all

Changing my fueling/spark timing will only cause AFR to go up & down, but idle speed doesn't change.

I'm out of ideas.... any suggestion what else I can look?

What is your EFI Brain brand??
