I think the moral of the story here is that your DeLorean should be *driven*. A bottle of STP cannot reverse of the effects of months or years of storage. When I first received my car, it surged horribly at idle as the previous owner had driven less than 1000 miles per year for several years. After daily driving for a few days the surges diminished and within 2-3 weeks receeded completely. The enemy of your car is Time, not Miles.
