back when i first got my mustang it wasnt summer yet, my idle was perfect then.


Its really hot nowadays, the idle is fine, its that it just sorta surges for a couple secs when i start up in the morning or something....

And it idles a tad lower???
i assume this is normal for warmer temps??

And how can i adjust my idle, my old 2.3l stang had a screw and this one doesnt....

Here is a write up on resetting the idle. Each page addresses a different aspect of cleaning and resetting idle related components.

In Warm weather, the cold idle can be slightly lower in my experience.

Good luck.
