will it hurt the IAC valve if I try to tug it off hard? or should I not do that. I cleaned the throttle body and inside and out already. Just need to clean the IAC. but wont come off maybe I need to tug it off.

IF you didn't get the IAC valve off than you haven't cleaned the TB "inside and out"... There is a large cavity where the IAC sits that will be VERY dirty.
