High Speed Idle

Are you sure the throttle or throttle cable is not sticking or binding? Though it could be many other things.

Other issue might be the idle air control valve.

The TPS was not adjustable. The screw holes were not slotted. It just went on and would not rotate. I assumed it was different from the ones referred to in TPS posts I found here.
I will check the cable to see if it is sticking or dragging.
I did not think about the IAC. I will look at it next. Is there anything I should do or know before pulling it off? Tests?
Thanks for the help!

It hasn't been cold enough in houston yet to see if it actually fixed the problem though......

As for the next step.....not sure, you may need to have it professionally diagnosed or get an OBD2 scanner to see if the IAC valve or other sensors are within specs.

Not sure and I haven't try it on mine, but have you try loosening the screw to the left of the throttle body yet? Perhaps it may help.

Is there any way to test the IAC? Everything seems to keep point at it.

With that car, and the fact everything is electronic, you are going to need to diagnois it from the computer, which means taking it somewhere, or buying the scan tool/software to do it yourself.
Right now, I honestly wouldn't waste any more effort and time doing anything else.

I am surprised Josh hasn't suggested the coolant temp sensor - he always seems to do so with this sort of problem, so I thought I'd bring it up.

There are two temp sensors. A single wire sensor for the dash, and a two wire sensor for the ECU.
It really sounds like the sensor is bad, and it's telling the ECU the engine is cold, when it's really not. So you are getting an extremely rich mixture, and the high idle. The sensor is like 20 bucks from liberty subaru www.newsubaru.com
