How to Replace an Idle Air Control on a 2004 SRT4

The 2004 Dodge SRT-4 is a Dodge Neon with an inline-four, turbocharged engine. The engine, at 148 cc, puts out 230 base horsepower at 5,300 RPM and 250 foot-pounds of torque between 2,200 and 4,400 horsepower. The idle air control (IAC) motor is mounted on the throttle body. The IAC sends a signal to the motor to open and close the pintle, as needed, to raise or lower the RPM of the vehicle at idle.

Instructions

1

Disconnect the negative battery cable with the appropriate wrench. Set it aside, ensuring that it does not touch metal.

2

Unplug the IAC motor's electrical connector with your fingers. Remove the mounting bolts with the appropriate socket. Remove the IAC from the engine, ensuring that the O-ring comes off with the motor.

3

Check that the new motor has a new O-ring installed on it. Fit the idle air control motor into the throttle body. Install the mounting screws and tighten them to 40 inch-pounds of torque with a wrench. Plug in the electrical connector.

4

Verify that the pintle on the new IAC is retracted. If the pintle is longer than 1 inch, reconnect the negative battery cable, plug the wiring harness connector into the IAC motor, plug a scan tool into the data link connector and use the open/close test to retract the pintle.
