Are you having problems with your vehicle's RPM fluctuating high and low ? Does it occur more often while running your A/C and/or other high powered auxiliary items? Does your engine sometimes even shut off? It maybe due to your Idle Air Control (IAC) Motor sticking from carbon deposits built up in it over time, causing the spring to no longer regulate the proper power to both your engine and other equipment. But don't worry, replacement is quick and easy by following these simple steps.
Items You'll Need:
1. A new IAC Motor
2. A Socket Wrench w/ 10mm socket
3. A new gasket (optional depending on condition of current gasket)
Step 1: Locate the IAC Motor
First, pop the hood of your Mustang and locate your IAC motor. The motor is located on the passenger side toward the back of the hood.
Step 2: Disconnect the Wire Harness From the IAC Motor
Next, locate and remove the wiring harness that is connected to the IAC Motor. This connection should pop off rather easily without much effort.
Step 3: Remove the Bolts From the IAC Motor
Next locate the two bolts (one on top, the other on the bottom) and using your 10mm socket & wrench, remove the bolts. Be careful, once you remove the bolts, the motor will be completely unattached and will likely fall off if not supported. Also, if you are planning on re-using the current gasket make sure to support the motor once the bolts are removed so that the gasket doesn't become damaged from falling to the ground.
Step 4: Bolt, Connect, and Done!
Once the old IAC Motor has been removed, all that's left is bolting the new IAC motor (with the gasket) back to the Mustang by following the previously listed instructions in reverse order (i.e. use 10mm socket & wrench to bolt new IAC motor and gasket back on, connect the wire harness connector back into the new IAC motor, and close the hood because you're done!)
