Idle RPM's

[DDorbandt]

I have asked around and noticed that most people idle around 600-800 RPMs for their 1995 GT. What would make mine idle around 450-500 RPMs? Is there any way to raise the idle RPMs? Does it have to do with the fact that my mustang is automatic ?

I would check your TPS on the throttle body.
Also there is a little screw on the TB that takes a flat head screw dirver blade. Turn that a little witht he engine running. I can't remember which way to turn it, but you'll figure it out. Just listen to the motor.

would turning that change anything in my performace? Or would it jsut change the idle RPMs up a bit? Thanks

your car will feel better if you bump it up. i tried bumping mine up and turning the idle screw did nothing at all. i don't know why. anyone have any ideas?
