Just out of curiosity, how (if at all) does the throttle body motor tie into this? I recently had it replaced when the car did not want to stay running at all. That did the trick, but now that I am again having a problem ( two months later) I wonder if the part that they used is in some way defective and causing me this additional headache. Your assistance is appreciated.
What should be used to clean the idle control valve? Does the valve need to be taken apart or just taken off and soaked? Is there an additive that can be used to clean it? I have P0505 DTC set on my highlander and would like to try this before spending any money on it!
