P0507 Idle Air Control System RPM Higher Than Expected

quite a few things, Bad IAC, dirty maf, dirty or bad throttle body/butterfly, air's getting past the throttle body where it shouldn't usually.

I always get this 0507

Do you think this has something to do with the ITG filter?
I bought the car with this setup and I had no Mil for 8000 miles and now I can't drive more than 100 miles without this anoying orange light turning on on my stack...

I already cleaned the MAF, the buterfly and the IAC, both were dusty and the IAC is no turning smoothly as a new one (stil some tiny rought spots while turning it with my fingers)

Any ideas?

Thanx

I just got this code today. First, what's an IAC? Sorry if its a dumb question, I'm an old man that spent the last 12 years driving a '66 Jaguar E-type.

What are appropriate actions to take?

Idle Air Control. Electronic part connected to the Throttle body.

Thanks Mr. Know, now can anybody tell me WHY IN THE HELL LotusGarage wants $504.78 for this part???? Is it a Toyota part?

Before replacing this part is there any other action I should take?

The part circled in that photo is the TPS.

The IAC valve on the 05's can be had for around $215 from RockAuto or slightly more from any Toyota dealer.
