e350 idle speed
I have a 1993 E350 van (actually a conversion bus, but with an e350 front end) that is idling a little low. It pushes 14.5v to the battery at idle, but with headlights or any other accessories on, it drops down to 11.5-12v...draining the battery. My alternator/starter service, who just replaced the alt has told me I need to adjust the idle speed up enough to keep it at about 14v with the lights on at idle. Where is the idle adjustment on this van?
