idle air controller

what is the best thing to clean an idle air control sensor? starting fluid, carb and choke cleaner or brake parts cleaner?
this is on a 97 gran prix with a 3800 series 2 v6.

thats the IAC, or Idle Air Control, its a stepper motor.
you can clean it with spray carb cleaner.
starting fluid won't do much and brake clean won't do anything.
normally you don't need to pull it out of the throttle body, just spray some carb cleaner into the port where its at. it doesn't take a lot of cleaner, just a shot for a couple of
seconds. if you can, start the motor up & give a few shots of spray waiting a few seconds between spraying it.
if you do pull it out to clean i, don't pull the pintle all the way out of it, that usually will damage it.

You can also use Kero or Hydrocarbon based cleaning solvent as well. Watchout for the O Ring seal.

brake cleaner and carb cleaner are basicly the same thing. with carb cleaner being only a tad more harsh

Rumor has it that some of those parts have an anti-corrosion coating on them that can be damaged by ordinary carb sprays. Dedicated throttle-body cleaner supposedly won't damage the coating, so that's what I use on mine.

not the carb & brake cleaners i use.
the brake cleaner i use won't cut into the paint in seconds like the carb cleaner will.
the carb cleaner i use will etch the paint in just a few seconds. if its left on the paint for 30 seconds, it just may take it down to bare metal.
