First, have you checked for vacuum leaks? and how long do you let it warm up? And, have you tried adjusting the idle screw? just trying to get an idea of what you have and haven't done to diagnose the problem.

i second that adjust the idle screw. there is load a little load on the engine with an automatic transmissions at idle, however with a manual transmission there's little to none. therefore it makes sense that this is an issue for you. tighten the screw on the iacv it should lower the idle. also read your fsm about idle adjustments. once you have the correct idle rpm, verify your base timing is 20 degrees btdc.

i also recommend you try unplugging the kickdown (wide open throttle) switch that's on your tps, it's the 2 wire plug.
