1983 928S 5Speed Idle Surging?
i have 1983 porsche 928s 5speed with a idle surging at start up the rpm go up and down from 650 to 1800 even when it warms up its still the same. the car drive fine when you are in gear driving around. so far i replaced the spark plugs, checked/fix vacuum lines, replaced both orings on the throttle body. anyone have ideas what it could be? thanks
