On my new manual 2006 V6 something’s weird's going on....when I’m about to park or stop, say I was in 3rd gear and I’m about to stop: I go into neutral, im pretty much stopped I let go of the clutch and the gas (now going about 5 miles per hour) I’m braking while in neutral and the engine keeps revving up it goes up almost a 1000RPMs (just like if I was hitting the gas pedal--which I though I might of been accidentally with the side of muy foot but even when I take my feet well away from the pedals this still happens...) When that happens, if I floor the clutch than it stabilizes if not the RPMs go up and that after a little bit settle down……what‘s up….???.

 

Have you ever cleaned your IAC? This sounds like a textbook case of a sticking IAC valve.

Edit: Well, if you just bought it, the IAC could stand to be cleaned probably... Look around, there's tutorials on how to do it. Basically when you get it off, spray a generous amount of carb cleaner in it.

Edit again: I've found when my stang is rolling and in neutral, the RPM will stay at about 1200... as soon as I come to a complete stop, the RPMs will drop to 800. If this is what it is doing, then it's normal.

 

yeah mine revs to if i take it out of gear while coasting down the highway.
eventually settles down.
as long as it doesn't go above 1300 id say its normal

 

can you adjust the throttle position sensor on those things?

 

Thats the thing , it goes up to even almost 3000RPMs...thatnks for the replies though....
