Steps
Remove the intake connections
Let the engine cool and disconnect the intake duct and electrical connectors. Release the throttle-body bracket and fasteners, then lift the throttle body off without damaging its gasket or wiring.
Clean the throttle plate
Use cleaner intended for throttle bodies and a soft nylon brush. Wipe deposits from the plate and bore gently; avoid soaking electronics or forcing an electronic throttle plate.
Reinstall the throttle body
Seat the throttle body with its gasket in the correct position and tighten fasteners evenly to specification. Reattach its electrical connector and support bracket.
Reconnect the intake and check
Reconnect the intake duct, sensor, and any displaced hoses, then tighten the clamp. Start the engine and check for warning lights, unstable idle, or intake leaks.
Check your vehicle’s repair manual for exact specifications and fit.
