So I'm still trying to figure out why she won't idle right.. cobra intake, f303 cam and aluminum heads with 24# injectors and 24# maf. Haven't installed the better fuel pump yet.

Every time I start it, the idle either jumps around a lot or it stalls. I've adjusted the TPS a bunch but I'm out of ideas. Anyone know??

Have you checked for a vacuum leak? Will the car run if you keep the rpm up? Backfire choking popping?

You guys with idle/stall problems could save a lot of time chasing your tails if you would go through the Surging Idle Checklist. Over 50 different people contributed information to it. The first two posts have all the fixes, and steps through the how to find and fix your idle problems without spending a lot of time and money. It includes how to dump the computer codes quickly and simply as one of the first steps. I continue to update it as more people post fixes or ask questions. You can post questions to that sticky and have your name and idle problem recognized. The guys with original problems and fixes get their posts added to the main fix.

It's free, I don't get anything for the use of it except knowing I helped a fellow Mustang enthusiast with his car. At last check, it had more than 250,000 hits, which indicates it does help fix idle problems quickly and inexpensively.

Thanks for the link. I'm not familiar with these forums too much. And I had the whole system checked for vacuum leaks and vapor tested

Take a deep breath, make sure your wiring and all the grounds have good connections, go throught jrichker's surging idle checklist, you'll find something you missed.
