setting TPS using Rtek

With engine fully warm, what is the normal TPS percentage it should read at idle? My car idles roughly at 1000 with no emissions present. Its gona stumble and die if i bring the RPMS down with the fast idle cam. Im pretty sure i have a vac leak present but i want to make sure my TPS is ruled out as a idle hunting issue before i start looking at hoses.

dose it matter what rpm the idle is at? or is the 20% @750 rpm?

When the throttle is close it should be 20%. What RPM the engine happens to be is irrelevant...

i had it set at 20%, and it seemed to low. the car would buck a lot when slightly decelerating. I have found 25-28% works a little better, and still goes into decel fuel cut when off the throttle. it could be related to my throttle stop setting though, i have no bac valve, my idle is set with the throttle stop screw
