After a few days idle or after a rainy spell the throttle on my car is slugish to return to idle. It seem to hang up about 1000 rpm untill i punch it a few times to get it to release. Warming up seems to help. I have lubricated all the linkages I can see on the top of the engine without relief. An I missing something?
