I have complained of a rough or vibrating type idle either in or out of gear on my 5 speed Getrag Automatic Transmission car. Hot or cold. Feels like a motor mount missing or something. Dealer Tech comes up with the following: Puma Case 4903607 - Re Program DME and clear Adaptation Values. Advise customer to change Fuel Brand. I had been using Mobil Premium so to day I filled up with Chevron as recommended. It was either that or Shell and I couldn't find a Shell station. Car runs like a jack rabbit other than that. Only time it ever shuts down is on a hard right turn and I can live with that. Any ideas. Oh yes car has 35K on a wonderful set of Michelin PilotA/S purchased from the Rack. Bought the car new from dealer who is servicing it. Thanks for your ideas.
