1. Remove the idle air control (IAC) valve connector. 2. Remove the IAC valve attaching screws (1). NOTE: If the IAC valve has been in service: DO NOT push or pull on the IAC valve pintle. The force required to move the pintle may damage the threads on the worm drive. Also, DO NOT soak the IAC valve in any liquid cleaner or solvent, as damage may result. 3. Remove the IAC valve assembly (2). ^ Clean the IAC valve O-ring sealing surface, the pintle valve seat, and the air passage. ^ The IAC valve may be cleaned. Use a shop towel or parts cleaning brush to remove any heavy deposits. ^ Any shiny spots on the pintle or seat are normal and do not indicate misalignment or a bent pintle shaft. ^ If the air passage have heavy deposits, remove the throttle body for a complete cleaning. ^ Inspect the IAC valve O-ring for cuts, cracks, or distortion. Replace the O-rings if necessary. ^ When installing a new IAC valve, be sure to replace the valve with an identical part. The IAC valve pintle shape and diameter are designed for a specific application. MEASUREMENT PROCEDURE This procedure is only for installing a new IAC valve. IMPORTANT: If installing a new IAC valve, replace the IAC valve with an identical part. The IAC valve pintle shape and diameter are designed for the specific application. Measure the distance between tip of the IAC valve pintle and the mounting flange. If the distance is more than 28 mm (1.1 in), use finger pressure to slowly retract the pintle. The force required to retract the pintle of a new valve will not cause damage to the valve. INSTALLATION PROCEDURE

Exhaust System Removal Note: With a used vehicle, we suggest a penetrating spray lubricant to be applied liberally to all exhaust fasteners and al- lowing a significant period of time for the chemical to lubricate the threads before attempting to disassemble. 1. Unbolt the flange located just in front of the rear muffler as shown in. (figure 1) 2. Lubricate all the hangers and rubber isolators. 3. Using a muffler stand or an additional person to hold the rear muffler into position, remove the hangers from the rub- ber isolators and remove the rear muffler from the vehicle as shown. (figure 2) 4. Unbolt the flange located just behind the catalytic converter as shown. (figure 3) 5. Place hardware and gasket to the side for use during the installation of your new exhaust system. Using a muffler stand or an additional person to hold the front muffler assembly into position, remove the bolt from the rubber isolator and remove the front muffler assembly from the vehicle as shown. (figure 4) 1. Using the original hardware and gasket, place the muffler assembly into position as shown. Hand tighten the hardware for now. (figure 5) 2. Place a clamp over the expanded end of the intermediate pipe and set it into position as shown making sure to install the hanger into the rubber isolator. Do Not tighten the clamp. (figure 6) 3. Place a clamp over the expanded end of the tail pipe assem- bly and set it into position as shown making sure to install the hangers into the rubber isolators. Do Not tighten the clamp. (figure 7) 4. Check your exhaust system for proper clearance under the vehicle and also for tip alignment.
