Cleaning a Throttle Body

October 24, 6:30 PM [GMT -5]

This is a common problem, the build of residue, or "coking" on the back side of the throttle plate.
However, it is recommended to spray the cleaner onto a rag or towel, open the throttle plate, and wipe off the coking from the throttle plate and the inside of the throttle bore.
Most major automotive manufacturers actually do not recommend cleaning the throttle plate due to the use of these sealed bearings.
Most newer vehicles use sealed bearings for the throttle plate shaft, and the cleaners used will damage the seals and bearings resulting in a sticking or binding throttle plate. You may actually damage the throttle plate to tune of about $100-200 for a non-electronic controlled throttle body, If you have a vehicle with an electronically controlled throttle body ("drive by wire"), your replacement cost could $400 on up.
Review any service information for the applicable vehicle before proceeding, and use the above mentioned procedure cleaning process if you need to proceed.
