I noticed that my mustang has a really high idle. Yesterday it was at 2 grand - :\

Also sometimes it seems to just be all over the place from 1 grand to 1.5 to 2.

I am going to clean out the IAC and check the Throttle body today.

Is there anything else I should do?

check your tps voltage

 

clean out your IAC valve and then reset your computer by taking the neg terminal off the batt for like 30 minutes... it that doesn't help there's a screw in the back of the tb that you can turn to lower the idle

 

Thanks for the suggestion.

check all your vacuum lines make sure none crack or split

 

My brother and I cleaned out the IAC and the Throttle body lastnight and that helped some (atleast the gas pedal doesn't stick anymore - )

I will check the other stuff as well.

Clean your MAF too, reset the computer and play with the idle adjustment screw some.

 

It's an 87 still has SD -

Change the TPS, my car idled at 2000 when it went bad.
