Hi All. When not driving my D in the winter months, I try to take it down to the local Dunkin Donuts for a run every Sunday (If the roads are dry). But lately I have noticed this growing problem and concern. While my D is warming up the idle speed is erratic, I have noticed that the upper and lower engine peaks have gotten progressively worse. I like to let my D warm up before driving (approx 5mins). I can almost tell that my D has warmed up as the pulsations decrease in their aggressiveness. After she's warm all is well. Although I don't think of a Delorean as a she. Q. If J. Delorean for some reason was unable to make new DMCx2. Could DMC Houston. ? There are no words to explain how I feel when I get behind the wheel of the greatest car ever made. Thanks J.D and all DMC friends. Declan Kelly Boston MA. Dubliner.
