Symptoms Of A Muddied Throttle Body

These are the nigh common symptoms of a muddy electronic throttle trunk:

  1. Sticky gas pedal sensation felt as a hesitation when you accelerate the engine.
  2. Rough idle.
  3. Failure of the Throttle Actuator Command (TAC) motor drive gears.

  1. The cleaning spray that you use must not comprise Methyl Ethyl Ketone (MEK).
    1. This means that you lot can not use most (if not all) brands of carburetor cleaner spray.
    2. Methyl ethyl ketone is not corrosive for metals, but attacks certain plastics and materials including natural safety, nitrile rubber, polyvinyl chloride, Viton®, certain acrylics and celluloses.
    3. These are the materials almost of the components on the intake manifold, plastic plenum, and the insides of the electronic throttle body are made up of on your GM vehicle.
    4. Other Names for MEK: 2-Butanone;  Butanone;  Methyl acetone;  Butan-2-i;  Methylpropane-2;  Butanone-2;  ii-oxobutane;  three-Butanone;  Ethyl methyl ketone;  Methylethylketone;  Ethylmethylketone
  2. The recommended throttle cleaner is the: CRC 05078 Throttle Body and Air-Intake Cleaner - 12 Wt Oz..
  3. You should NOT use whatsoever type of scraper tool or spiral commuter to scrape of the deposits that have accumulated on the throttle plate or throttle bore.
    1. Physically scraping the deposits will go out gouges in the soft aluminum metal the throttle body is fabricated upward of and this will affect idle quality.
