trouble with idle, rpms wont drop

[D347643]

ok when i rev my car up and then let off the rpms drop and hovers at about 1100 and then slowly fall to about 750 where my idle is. Is that normal?

thanks,.

I refer to what you are talking about as a hanging idle. Mine does this too, and has gotten a little worse since I put a new MAF sensor on. I am going to check and make sure my TPS it where it should be and set my idle where I want it with the IAB disconnected. Im going to try that tomorrow. I'll let you know if it cures the problem.
