    Cool Throttle Body Cleaning

    Just spraying some stuff, or wrapping a rag around my finger and opening the Throttle and wiping it from the outside, does NOT seem professional, I have NEVER done one, but have done carburetors. Should I pull it and clean it, will Anti Freeze come out ? Do I need a New gasket, and/or gasket sealer ? Is there help for a Throttle Body dummy ? Thanks

    Re: Throttle Body Cleaning

    I frequent another forum for my Saab 9-7x, think Envoy or Trailblazer, and the recommendation is to remove the throttle body to clean and disconnect the battery for
    a couple of hours to relearn throttle position. Seems the PCM compensates as the throttle body acquires crud. The throttle body is usually dirtier on the back side. I have no idea if this is the same procedure with our Cadillacs.

    Re: Throttle Body Cleaning

    This does make sense. It also makes sense to do it regularly, even if one uses Top Tier fuel and Techron once in a while. If there is any contact between the throttle plate & body at all, deposits seem more likely to act as an abrasive than a lubricant. Once a groove forms, anything short of a new throttle body is a hack.

    There was a point with my 2006 that the throttle seemed a bit touchy when leaving a stop. I'd either launch or leave slower than intended and then have a bit of a surge. After a TB cleaning, I had a lot better control and with the TCM programming in the 1SG, throttle control is big part of driving fun.

    Actually, I'm overdue!

    Re: Throttle Body Cleaning

    I must be the lucky one. My '06 STS AWD V8 has about 60k miles and the throttle body is still as slick and clean as the day the car was delivered. I've had it apart several times for other projects and have never found deposits of any kind in or around the throttle body or intake system.
    Don't mess with Binky Bear!
