After i plugged my heater hoses, whenever i put the car in park after driving, the idle goes super high....like `1500 to 2k....i tap the gas to bring the idle down, and it just hovers higher...then, i turn the wheel, or press on the brake, and the idle starts to go down....sometimes when i would be at a stoplight, the idle would be kinda high, like at 1000 or so, isnt normal idle speed like 650 or 700? i wonder if this is still the IAC?
