Idling issue

So Ive got an 03 GT. sometimes when I start it up it will idle perfect and other random times itll go from idle speed to almost shutting off then jumps back up and keeps doin that. I drive it, come to a stop again and its gone. And it does it randomly... Whats the deal?

I'm sure a mod can/will move it for you but with what you are describing it could be numerous things but first thing that comes to mind is you have a vaccum leak somewhere

Agreed ^^^ a vacuum leak or a dirty MAF sensor can easily cause this issue. If that doesnt fix ur issue check ur tune by sending a data log they can pin point the issue sometimes, then check ur intake system, spark plugs, stuff that has to do with ur car idling and running.
