What are the signs of a bad IAC Valve?

Clean the ac out and see if it helps. It's not long term fix but it will at least let you know it's the isc.

Thanks. I'll give that try.

Adding stabilizer to already bad gas isn't going to help. I'd get that gas out of there asap, and not running it through the engine.
