Throttle Body Cleaning
Carbon and sludge removed from the bore, plate and idle passages.
Carbon and oil vapour build up on the throttle plate and bore, disrupting airflow and causing rough idle, hesitation, stalling and sometimes limp mode. Ultrasonic cleaning removes it evenly without scratching the bore or forcing solvent into the throttle position sensor.
We clean drive-by-wire and cable throttle bodies, taking care around electronic actuators and sensors.
What we clean
- Electronic (drive-by-wire) throttle bodies
- Cable throttle bodies
- Idle air control valves
- Intake elbows & plenums (small)
- Throttle plates & spindles
What's included
- Careful masking of electronics
- Ultrasonic cleaning of bore & plate
- Idle passage clearing
- Rinse, dry & lubricate spindle
- Inspection report
Our process
Mask & protect
Motors and sensors are protected or removed where possible before cleaning.
Ultrasonic clean
The body, plate and idle passages are cleaned to remove carbon and oily film.
Dry & inspect
The unit is dried, the spindle lightly lubricated and function checked.
Benefits
- Smoother idle & throttle response
- Clears hesitation and stalling
- Even, scratch-free cleaning
- Protects sensitive electronics
Frequently asked questions
Will I need to reset the throttle adaptation?
Often yes — many cars relearn idle automatically, some need a diagnostic reset. Your garage can do this on refit.
Petrol Injectors
Ultrasonic clean, flow-tested and re-sealed — like-new spray pattern.
Diesel Injectors
Deep ultrasonic decarbonising of diesel injector bodies and nozzles.
Carburettors
Every jet, passage and emulsion tube cleared — carbs that run right again.
