Anyone know how to remove IAC Valve ?

[Pressed]

I need to remove and clean my IAC valve. I'm sure this is an old topic but I can't locate it. Can I just unscrew it from the throttle body, undo the electrical connections and clean with throttle body cleaner or what ? My ride has been plagued with a relatively low idle since purchased (@ 650 RPMS at warm idle with little blips occasionally stretching up towards 700 tops) Is it as straight forward as it appears to be ? Any help is appreciated

My bad, a 1999 996 Cabrio 6 spd manual on the above.

Personally I like to remove the whole throttle body and the clean the throttle buttery front and back.

As well remove the IAC being protective of the paper gasket and clean it until it moves freely. If it does not move freely it will need to be replaced.

 

Here is a DIY article that pretty much covers it (though it is an egas car).

Really is best to remove the whole Throttle body and then remove the ICV.  Then you can access the screws holding the ICV to the TB easily.  Use a 9V battery to operate the ICV back and forth, otherwise you will not get it cleaned out properly.  Be very careful with the paper gasket, it tears easily.  I used throttle body cleaner, soaked it overnight, then clean out the crevices with Q-tips while operating the ICV with a 9V battery.  Then blow the whole assembly clean.  Meanwhile, clean out the TB.  It really is a pretty simple job.

Thanks to the both of you for the advice given. I do understand that a better cleaning will result from removing the whole to ensure a better cleaning of both after separation. Can you tell me what type of screwdriver I require to take the IAC valve off of the TB ? The bolt on the IAC resembles an allen key kinda deal.

It's a Torx head screw.  Either a Torx bit or Torx screwdriver will work, however I forget the size.  I have both sets and just find one that fits.

Thanks, DBJoe. I just happen to have a set of the Torx head bits.
