Can a IAC motor be removed from a Mustang?
Can a IAC motor be removed from a Mustang?
The IAC has an electrical plug that needs to be disconnected (picture 2 “C”) Then all you have to do is remove the two 8mm-5/16″ bolts (Picture 2 “A”) that hold the IAC to the throttle body or intake. Watch out for the IAC motor to throttle body gasket, don’t lose it!
How does the fuel injected Mustang engine work?
The fuel injected Mustang uses a small motor/valve assembly that allows a specific amount of air to enter the engine to control it’s idle. This valve is comonly called the idle motor, the IAC (idle air control) or the IAB (Idle air bypass). When your car is new the IAC works remarkably well.
What is the idle motor on a Mustang?
What this series of articles is aimed at is how to fix the most common idle problems found in the Mustang. The fuel injected Mustang uses a small motor/valve assembly that allows a specific amount of air to enter the engine to control it’s idle. This valve is comonly called the idle motor, the IAC (idle air control) or the IAB (Idle air bypass).
How does the engine run with IAC disconnected?
The throttle is set to allow enough air to pass so that the engine will run in neutral under ideal conditions and the IAC adds to that flow enough air to bring the idle up to the programmed speed. Everything in the throttle body must be clean in order for everything to operate properly.

What does a Ford IAC IAB look like?
In reality once you know what one looks like (picture 2 “B” from a 94-95, fox body’s have longer silver IACs) you should have no trouble finding yours. They all look basically the same except pre-94 cars were made of metal and are silver, 94-up cars are black plastic.
What causes idle problems in a Ford Mustang?
In this age of fuel injection, idle problems can literally be caused by hundreds of different things. What this series of articles is aimed at is how to fix the most common idle problems found in the Mustang. The fuel injected Mustang uses a small motor/valve assembly that allows a specific amount of air to enter the engine to control it’s idle.
Why does my car stall at low rpm?
The will likely force your computer to stall the engine and only allow it to run at low RPMs, which means the car will only move at slow speeds. This is a safety feature enforced by the computer so that your engine doesn’t get too damaged.
What to do about slow RPMs on a Mustang?
As a side effect of this fix, when you downshift, the car burbles a lot more, sounds like a carburated engine. You get a little more engine braking effect. Most older mustangs have an external IAC valve. Meaning that it is easy to find, follow a small air hose (1/2″ ID) to a silver cylinder thing on your intake (the IAC solenoid).
Why do my RPMs drop when I start my car?
After your “restricter plate” is cut out, mount it with the small hole on the passenger side of the IAC, and make sure to replace the gasket against the intake. Start your car, you should notice the RPMs drop when you start back to normal very quickly. If it idles smoothly, try putting turning on the AC, this will load the engine down.
Why does my Ford Mustang burble when I downshift?
The engine is recieving too much air through the IAC valve. From my knowledge Ford did this for emissions reasons. As a side effect of this fix, when you downshift, the car burbles a lot more, sounds like a carburated engine. You get a little more engine braking effect. Most older mustangs have an external IAC valve.
How do you fix a Mustang air intake?
Most older mustangs have an external IAC valve. Meaning that it is easy to find, follow a small air hose (1/2″ ID) to a silver cylinder thing on your intake (the IAC solenoid). Once you found it, the older fix was to buy a 1/2″ copper pipe cap, drill out a small hole, insert this into the line the restrict air flow through the IAC, and your done.

What is the idle air control valve on a Ford Mustang?
Change out the faulty part with a new Ford Mustang idle air control valve from AutoZone. A Mustang IAC valve controls airflow coming into the engine so that it gets the right amount of fuel. Dirt and carbon blocks the airflow, sending wrong information to your Mustang’s computer.
