As soon as you start a delorean its idle should seek for a brief period of time. It should go from like 500 to 1200 rpms for a minute or to if it is cold. My delorean which is noy getting the best gas milage and has a perfectly running frequency valve does not rev at start up. It starts up and holds an idle perfectly. I would like my car to have a proper delorean idle, and I tried adjusting the CO screw (1/2 turn) to lean, but this changed nothing what would make my car not idle like all of her other delorean bretheren. Any ideas btw I know this may sound silly, that I want my car to seek for an idle, but I think this may be someway related to my gas problem, anyway, what makes the normal delorean idle seek occur and what can I check?
