So I've been having an idling problem with my car. It will idle fine at about 17-18 lbs vacuum, but every 2-3 minutes, it will try to die. It will then rev up to save itself after trying for about 3 seconds or so. Fuel pressure is fine on the car and all my gauges read fine. I don't have a data logger, I do have a ced, but I figure it's at least the stupid egr triggering that. Toss me some ideas of what to check or if you need more info on it to throw out suggestions. I'm thinking it could be the IAC, so I will give that a looksee, but what else?

Does it when the car is warm.

I know what FINE means but it doesn't work for fuel pressure.

What is the fp at idle?

What are you using to raise the fuel pressure under boost?

I just got the aeromotive 1:1 installed. It was doing the same thing before i installed it. I thought it was from my 440's until I got the fuel pressure under control. I have it set to stock around 43 psi =/- .5 psi. Fine tuning is controlled by the emanage which corrects for the injector change.
