I pulled the IAC on my 91 GTA 5.7 and I was wondering if I should be able to push in the needle against the spring. When I do push it doesn't move a lick, completely stuck and hard. I thought it should be free to move unless it only moves with electrical current. Was wondering if since it does not move by a push of my finger if it was stuck and bad. Although I thought it seemed to be working when it was in the car. I could tell the idle would change when I would turn on the AC. Although I would get major loping when the car was completely to running temp. My fuel injectors were bad anyway and I am replacing them, that is why I have everything apart and decided to look inside the IAC hole and clean everything out. Pushed on pintle and doesn't move at ALL. Is this normal before I spend money on a new one?

 

I think it shouldn't move since the motor inside actually threads it in or out. You might just be feeling the play in the threads if you push it.

 

you should be able to rock it back and forth and actually push it in. if you are unable to move it in then it is bad.

 

Well my point is I feel no play at all. It does not move.

 

Thanks one92rs. This thing is frozen like a block of ice. Doesn't twist turn push in against spring nothing....I even tried pushing the pintle against a wall and it would not break loose.

 

If it is the original IAC, you should probably replace it. It sounds like it is not functional anyway. I think I payed about 20+ bucks for a new one.

 

I don't know where you got it for 20. They are like 80 at advance auto for the bwd.

 

Alright, I was thinking of the TPS. Sorry my mistake. By the way, did you take carb clearer and give it a good cleaning?
