on most B series FWD mazda motors its on the TB itself... it angles upward and slightly forward (toward the front of the car).

It is on all TB on the 4cyl's.
Before you check the idle speed make sure that all accessories are off (ie, radio, heater, a/c, lights). With the engine warm and the cooling fan OFF, you can make your adjustment btwn 750-850 RPM with a flat head screw driver. Your ignition timing should be set at 9-11 BTDC first before you adjust.
The adjustment screw will be obvious on the TB.

Will I have to readjust the idle when I change my TPS ?
