Default RPM's fall to near 0, then bounce up to normal

If I give the engine a rev in neutral at a stand still, the needle will fall down to near 0 and then bounce up to its normal idle.

I just replaced my spark plugs, MAF, Fuel Pump and cleaned my panel filter prior to all that. It's kind of annoying, because in lower speed turns my steering becomes tougher all of a sudden

Any ideas?

buy an iacv gasket
clean your iacv

you need the gasket because they often get destroyed removing the valve.
