Default sucked in water

Going through some pretty big puddles yesterday I sucked in some water. It takes a while to start and will only stay running if I am on the throttle, once I let off and it drops rpm's it dies, any suggestions?

Are you sure you sucked water into the intake, or just got the engine compartment wet?

Takes while to start, once it catches I need to stay on the throttle for it to stay running, when I let off the throttle it goes blub blub blub and dies

If the IAC got wet could that cause it?

I just had this problem after driving in some swamp, i sucked up water and had to replace the tps. I had the same symptoms you are describing.

I'm thinking you did not suck in water, but got sensors/connectors wet.

what sensors or connections would cause the motor to die at low rpms?

TPS, IAC, maybe CPS.....

Start unplugging them all and spraying the connectors out with contact cleaner.
