( Dan, Just to make sure were talking about the correct part, here is a link to the vacuum advance unit on the side of the ignition distributor. http://www.specialtauto.com/delorean-images/distvacadv.jpg The engine wouldn't perform well when I first started it and drove for the first 5 minutes, but then it was fine after. The idle speed would vary faster and slower up and down for the first 5 minutes too which I thought was odd, also the idle speed is quite high, around 1000. ( Dan, As far as fuel goes, the idle should be consistence because the Lambda control system should be holding the fuel at a 80/20 state till the 02 sensor heats up. Normally 2 min or less. but, if there is a vacuum leak the idle will vary, so you may have more than one thing going on at a time.) John Hervey > Is this the effects of my bad leaking advance?
