OK, I went out of town with the Sportage. I stopped at a station and got some gas. Soon after, I picked up a intermittent miss.

It acts just like water. It will miss any time the tank is sloshed... turning, darting, pulling uphill, taking off, etc... and I can make it miss really bad by "getting on it" when it misses.

I was certain it was water. I ran the tank near empty, then filled here locally and put some stuff in the tank. It did good for a while, but started back again... and now the tank is near empty again.

I'm starting to wonder now....

Any of you guys have a proven method to get rid of the water, or rule out that it is water?

I'd like to cure it or rule it out ASAP.
