Stuck throttle

[da89cup]

I bet if you unplug the wire connector from the IAC (the tube thingy you're talking about that's located beside the throtle body)your problem will go away. Just try it, & if your problem goes away then you'll know that's the problem. Make sure you do it after the engine is warm, otherwise the engine will want to stall. Instead of buying a new IAC, I just spliced the wires to a toggle switch that I put inside the car, & once the engine warms up I flick the switch & I turn the IAC off. NO MORE THROTLE STICKING!
