Am I missing something? Why do you want your engine to idle below 700 - 800? I thought 775 was the spec. On a properly operating engine, the idle speed is controlled by the Idle Speed Motor and its ECU not by any screw. Correct?

How low can a factory new engine idle? I have a new butterfly assembly, the whole thing not just the shaft and flies, Put in O-rings and checked every single vac line...With the adjustment screw missing I still get 7-8. Any ideas? -----Dani B. #5003 [Non-text portions of this message have been removed] To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
