Have cleaned IdleControl valve three times (as per numerous posts). Runs ok for a couple of days - but then the high idle returns.

HOWEVER, if I disconnect and then reconnect the lead wire (two pins) to ICV, idle immediatley returns to normal and stays great for a few more days.

My guess is that perhaps I have bad connection...or could ICU be sending an intermittent signal/power? Surely not....

Shall I clean ICV again?

Help?
