Stalls At Low Idle

[Ruben Rivera]

Hey guys I have a little problem here I got an 87 Foxbody 5.0 did a complete tune up fuel pump fuel filter and the car has a little bit sounds like its misfiring in low idle when I'm taking off on 1st gear after 2000 rpms is fine but just when it's in low RPMs it seems to stall any idea what it could be The car is completely stockAnd I check the timing and its good And I forgot to mention when I started up in the morning I have to rev it up a little hold the gas If not the car will die Hey when its still cold the idle just bounces up and down after Warm up it stops

Try cleaning the IAC valve on the throttle body. 9 times out of 10, that's what causes the problems you're describing.

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 200,000 hits, which indicates it does help fix idle problems quickly and inexpensively.
