Re: help high idel

first things first, can you run a stock hood like that and do you have any more pics!

are your throttle blades closing all the way? if they are, then I would check the IAC motor, and check for vacuum leaks.

Best of luck-

Eric

I doubt a tbi ECM can run that correctly, though I have only gathered information from the internet. The EBL would be plug and play http://dynamicefi.com/, you will also need a 2bar MAP sensor.

Wish I had such a toy to play with.
