Truck is idling weird in park and at complete stops. Keep my foot on gas to keep it idling at normal. Now has started stalling out and check engine light has been on. All signs out to idle air control valve. Found a new part just no luck finding it under the hood. Anyone able to help point me in right direction??

 

What motor do you have? 92 was the first year for the 5.2 magnum but if you have the 5.9 it still would be the LA.

 

it’s a dump truck. Believe it’s a 360 5.9. What do you mean by LA?

 

LA maybe the model. Like the 1994 would have started as a BR. It would be on the back of the throttle body assy. It will use torque screws or 5/16/8mm bolts.

 

The LA motor was the predecessor to the magnum. If it's 360 it should be the LA since the 360 magnum didn't come out till 93. They have an idle motor that actually moves the throttle to keep it idling(on drivers side). The magnum has a iac behind the throttle body.
