Question about 2004 Hyundai Santa Fe
After filling with gas the engine will start but will not idle. It will run at about 3000 rpm and I must put it in gear at this high rpm and drive about half a block before it runs normally until the next fill-up.
is the check engine light on, and have you checked the computer for trouble codes ?
Sounds like the idle air control valve is sticking but that would not have any effect with the gas tank.

SOURCE: fill up with gas
i had the same problem, you have to change the perge control valve, its on the back of the engine below where the plastic intake pipe meets the metal intake manifold on the back side of the engine between the engine block and the firewall, on the underside of your car hood you will see a vacume system diagram, it will illistrate where the valve is, it should cost about 30 bucks or so at a hyundai dealership

This is an article I found on gas. I have had this happen to me and if the gas goes bad in lawn mowers I'm sure the same thing will happen in cars just not as common due to cars usually don't sit around.
I would try putting a gas stabilizer in and run that tank of gas till almost empty then fill it and see if the problem is still there.
Also take a look under the hood and look at the wires and vacuum hoses animals seems to like chewing on them some times.
If none of this works repost but let us know if the battery was dead at any time and if the check engine come on while the engine is running.
