Have you had your battery terminals and wires checked, too?

Yup, and no luck.

Thought I'd dig this one back from the grave, was the issue ever resolved or is the Mach still stalling?

ZOMBIE THREAD FTL!!!!!!!!!!!!!!

i think he got it fixed.

Fixed. New IAC valve...had excessive carbon buildup.

I am still not feeling a sense of closure here? In post #74 the IAC was replaced with a new one and in post #77 it stalled again. Did the battery need unhooked to reset everything or what?

Either way, glad to hear it's fixed. That really sucks trying to chase something like that.

No, just an idiot driver. The way I was taught to drive manual transmissions was to put the shifter in neutral when you're slowing down...and well, that attributed greatly to the issue I was having. So I got the IAC replaced and changed my driving style and no more problems..

Half the fun of having manual, is being able to downshift to slow down and row the gears for fun :)
