With the engine off, use aerosol carburetor cleaner, a toothbrush, and a rag to clean the throttle body. Open the throttle plate to clean behind it. Do not clean the Throttle Position Sensor (TPS) or Idle Air Control (IAC) valve with the solvent.

1. Remove the windshield wiper motor and cowl assembly for access to the rear of the engine. 2. Remove the engine cover and both air inlet hoses. 3. Disconnect the hoses and remove the air filter housing. 4. Ensure the engine is cool, then drain sufficient engine coolant and disconnect the coolant hoses from the throttle body. 5. Disconnect the electrical connector and its clamp from the throttle body. 6. Remove the four throttle body mounting bolts and lift off the throttle body, discarding the O-ring seal if damaged. 7. Installation is the reverse of removal, ensuring the O-ring tab aligns with the intake manifold slot and tightening the bolts.
