my IACV is fux0red. a friend of mine did something in my integra where he 'tightened' its IACV and stopped the problem my teg is having. a few people have told me that my bouncing RPM problem could be due to air in the coolant lines. problem is, i cant locate a bleed on the h22a i have in my car. does the h22a even have a bleed valve?
