/\ Well, if that is the case, then your idle issues are from the thermowax and BAC being removed. Usually, you keep these things on the engine to improve it's idle quality.

Your TPS might be shot, so first go get another TPS, and thow it on and see what happens, this usually isnt the best way to fix problems, but for around $20 on the forums, it's nice to have a spare anyway...

You should build a twin-led tps adjuster( search) and adjust the tps to where only one led lights up... two leds mean it's too far and none means it's too close. Also check your throttle cable for smooth operation and binding. The cable on my TII sucks, atkins rotary and mazdatrix can get you replacement cables.

Depending on how cold it is in your area, when you remove the thermowax, you have to hold the gas pedal down a bit on a cold start.

The BAC valve then helps with idle quality.
