high idle

yess i searched but couldnt find my problem.

so my truck idles at about 1500 ALL THE TIME it doesnt matter if it cold of warm all the time and if i put on the ac it goes down to about 1100. i have loosened my adjuster screw all the way till its not touching. i have an iac restricter plate (home made) that made it stop surging at a stop and drop rpm much quicker and easyer shifts. but it was idleing high b4 that even. i already cleaned my iac but maby i need a new one what do u think? its a 1998 3.0 manual 5 speed

if the IAC is stuck it could cause a high idle. Its worth a shot to replace it
