Hello,

The idle air control motor is located in the throttle body either in the back or on the side. Here is a guide and some diagrams (Below) that will show you what Im talking about and some diagrams.

I just baught the grand am an noticed it needed intake gaskets we replaced the gaskets from intakes all the way up, after we changed them them the o2 sensor was reading bad, my first clue was the cadilac converter cause of the carbon build up that was in the throttle body, I cleaned it up, an flushed the engine twice due to the coolant being really nasty, brown. So when I took the converter off I noticed that it weighed aboout 60 lbs the honey comb inside of it was gone tons of sand. I changed that an the engine light went off. But noticed it had a slight of a idle issue when you started it it would idle extremely high at two thousand rpm. It would slowly drop down after a minute but sometimes wouldn't go down at all. No mind me the transmission had a little jerk a slight little jerk. But after I changed the (iac) for the idle noticed that the car don't idle up real high anymore it just idles up an down up an down now, an the transmissions jerk has become very seriously, where it'll jerk the whole car hard when shifting gears.

So do you have any codes now?Have you checked for codes since the idle is going up and down and the transmission is shifting hard?I would be looking for a vacuum leak also be checking the inlet air temp sensor.I have seen problems with the inlet air temp sensor connectors cause hard shifting.

I want to first start by saying that I am not trying to insult you.
Please try to use punctuation so I can better understand what is going on.

If I understand you so far, you have a high idle.
Did this happen before or after you replaced the idler air control?

I recently replaced my idle air control valve and now my car runs fine except my engine temperature gauge doesn't seem to read normal since then would changing this part possibly cause this problem

Sorry it took me so long to get back. I'm getting lunches ready for tomorrow.

I know the 2.8/3.1 engine very well.

Take the intake hose off of the throttle body.

You should be able to stall the engine if you put your thumb over the hole in the bottom of it right in front of the flapper, (the port that the idle control is connected to)

if it doesn't stall then you have a vacuum leak in the plenum or the intake manifold

I do not believe so it still runs fine and the gauge reads to a certain extent just never moves very far up there were wires around but I do not believe I touched any of them except for one that goes into the top of the intake towards where the throttle bore would be
