If accessible from a good angle Need to drill in to the broken part in the throttle body using a drill bit a bit smaller then the IAC thread as close as possible to the throttle body thread U need rethreading tap similar to the IAC valve if available in size and thread run thru to clean the throttle body thread and replace with new one if no access to it need take out throttle body U have to take Ur time.
Good Luck

How to remove a broken off IAC valve from the throttle body of 1994 GMC Sierra 4.3 liter? The threads are stuck in the inlet of the body


if there is an existing hole in what is left , try using a "easy out" tool of some sort, available from auto parts shop or quality tool stores
be careful and gentle as any removal tool will tend to expand what is left into the thread and make it harder to remove
if you have to drill a hole or enlarge a hole to get a tool involved . remove the throttle body from the engine so that metal swarf is not allowed to get into the engine

Where is the aic on a 94 sierra


Its located right on the throttle body. If your talking about the air intake temp sensor, thats mounted by the air filter or in the plastic tube that goes off the throttle body to the air box, its a 2 wire hook up. The idle air control "iac" is located on the throttle body side. "iac" idle air control. "ait" is air intake temp. 2 totally diff sensors.

Problem with idle


Check your Idle air control (IAC) valve wire leads. It's located on the throttle body, the other thing to is it may be dirty and will need to be cleaned with throttle body cleaner. That is just simple cleaning out the throttle body through out, paying attention to the IAC passage way in the throttle body intake. Once you cleaned out the carbon that should help your idle problem, the other thing that would cause this a dirty EGR valve and it's stuck. The EGR can also be cleaned with Throttle body cleaner by removing it and reinstalling it once all the carbon has been cleaned out. replacing the fuel filter also would not help and that is located in the inside frame rail under the drivers side and takes about 20 min to replace. Start with the simple and replace the fuel filter and clean and inspect the IAC at the throttle body. Good luck and keep me posted.

1994 gmc pickup- starts but when you put it in gear it dies, give it gas it will run but not good


It sound like your idle air control (IAC) valve is dirty and the fuel injectors. Try cleaning the throttle body and IAC with throttle body cleaner, if it's really bad you may have to use two cans of throttle body cleaner to make sure you have all of the carbon and varnish cleaned out. If this does not help, then there is a good chance that the IAC has gone bad and needs to be replaced but also check the wire harness to the IAC and TPS on the throttle body. Good luck and hope this helps and it would not hurt to replace the fuel filter also.

Stalls at idle no fluxuation in voltage at iac


It is most likely the EGR (Exhaust Gas Recirculation) valve.
The valve is supposed to close when the car is idling and open other wise.

Inspect it / Replace it.

Hope this helps!

Tps switch


The Throttle Position Sensor is a potertionmeter, and is connected to the throttle shaft on the throttle body it self. The best way to notice it, is the wire harness coming from the Throttle body on one side where the shaft is.

Good luck and hope this help.
