355 tpi iac adjustment

Ok so i finished my t5 swap but now everytime i have a really high idle i did a few test with brake cleaner spraying all vac lines an the intake an no high idle jump. So i did another test i pulled the air tube duct off the throttle body an stuck a rag in the bottom hole in the middle of the throttle body an the idle dropped a ton so it leaves me to think that the idle air control needs to be adjusted badly my idle is around 1200-1400 rpm
