|Throttle Body Cleaner and MAP Cleaner|
|Old can style|
There are five (5) ways you can service this throttle body for your car.
- Clean the unit off car and replace
- Clean the unit on car, engine off (OCEO)
- Clean the unit on car, engine running (OCER)
- Swap dirty unit for a precleaned backup unit
- Swap dirty unit for a new unit.
|Clean Throttle Body|
- General cleaning: Remove duct work to expose the intake side of the throttle body, set parts aside. Start engine, which will run roughly. Using your cleaner of choice, spray 1 or 2 second blasts into the unit, washing the throat and the butterfly plate. Continue till clean. Heavy deposits may require manual cleaning. An additional person is helpful to work the gas pedal as the engine will stumble as the cleaner is sprayed.
- Intermediate cleaning: This is done to maintain a previously clean unit. This is done as described as above or by the addition of a "spray cleaning" hole previously drilled into the duct work. You drill an 1/8" hole into the plastic duct work near the throttle body. This will be sealed by a sheet metal screw afterwards, which will then serve as your service port thereon. Remove the duct before drilling to catch any drill scraps. TO USE: remove the screw, with the engine running, spray blasts of cleaner into the hole using the straw that comes with the can (don't drop the straw, hold it with your fingers to be safe). Do this every 3 months to maintain the clean unit. There is no chance of puddling using this method and because it is concentrated, the small amount of carbon is easily removed. Every 9 months visually inspect the throttle body for additional cleaning.
It is a good time to also clean your map sensor using the proper cleaner.
