I'm going to change out the remaining coolant hose on my idle air control valve (the one on the driver's side), and it looks like to get at it I'm going to have to take off some of the vacuum plumbing,etc that's in the front of the valve. While I'm doing that, I wonder if I should take off the valve itself and clean it out. I've heard it usually gives no problems, but now would be the time to work on it if I can do something to prolong it's life. What do you guys think? Leave it be or take it off?
