From what I've read, this could be an airflow problem, which I'm going to out first. The MAF (Massive Air Flow) Sensor could be bad, and the air filter will likely also need replacing, especially after this terrible pollen season.
Here's how to change out the MAF sensor from eHow.com (http://www.ehow.com/how_4869741_replace-mass-air-flow-sensor.html)
Step 1
Open the hood to your vehicle and locate the engine air box. Check your owners manual for the location of the air box. In some vehicles, it can look boxy, in others, it may be cylindrical. Vehicle manufacturers do not always place the air box in the same location.Step 2
Locate the MAF sensor by opening the box that the new one came in and finding the same component inserted into the air tube running from the air box to the engine. The sensor comes in a variety of shapes and sizes depending on the vehicle, but most have an electrical plug the connects directly to them. Use the flathead screwdriver to release the lock and unplug the harness from the MAF sensor.Step 3
Open the air box and remove the air filter. On some vehicles, various screwdrivers may be needed including in some applications the use of a torx head screwdriver. Some air boxes have metal clips that require no tools and can be opened with the flick of a finger.Step 4
Disassemble the air tube on either side of the MAF sensor. In most applications there are band clamps present that can be loosened with a Phillips head screwdriver or a ratchet and socket.Step 5
Remove the old MAF sensor from the air tube assembly.Step 6
Install the new MAF sensor to the air tube and reassemble the tubes to either side of it. This will attach the air tube back to the air box cover.Step 7
Insert the new air filter into the air box and re-secure the cover.Step 8
Plug the harness back into the new MAF sensor outlet.
I'll post if this worked for me after I get the chance to fix it.
There's a few things that control the fuel flow and would make it idle high like that. The most common to go bad is the tps (throttle position sensor) which does exactly what it says. The next things to check would be the idle air control valve and the engine temperature sensor. If either of those parts "thinks" you're engine is cold it will pump way more fuel in than it needs, making it idle high. There's no good way to test any of those sensors or valves so it's a trial and error kind of thing. I would start with the least expensive part and go from there. The good thing is all of your sensors will be on the outside of the engine and very easy to get to. Let me know if y'all run into any trouble
