Sounds like a bad IAC valve. There's only 3 ways rpm's can go up:
You open the throttle blade
The IAC valve opens
You are not opening the TB
A vacuum leak will always be an increase in rpm....NEVER a decrease
The IAC can increase, decrease and stall the engine.
Go buy a new one and see if that fixes it. If it doesn't, return it.
Also.......a failing fuel pump or clogged fuel filter can cause a drop in rpm......but it can't cause an increase in rpm.
