After car warms up it will restart but rpms immediately dive and it cuts off. I tried pouring water on the top of the engine and it restarts perfectly. Flushed antifreeze and it helped a tiny bit

Flushing the cooling system should have nothing to do with what you describe. And, where did you pour the water in? Do you have, or have you had, a check engine light? If yes, you'll need to have the ECM scanned and give us the code #'s and the definitions. My first thought is the idle speed control (ISC) unit is malfunctioning. Please advise.

Cleaned IAC valve and it works OK. I had been told to do that about two years ago when it had different problems.I will donate more. Thanks

The car started fine but then has acceleration problems. Cleaning IAC helped. I poured the water around the plastic intake on the manifold and after 10 seconds it starts and runs right.

Billy, are you sure you don't have a vacuum leak somewhere around the intake area. You may want to check this out.
