I have had my 2004 automatic coupe (4400 miles) at the dealer 4 times since mid-April and will be going back again on Monday. I'm actually having 2 problems: 1) unpredictable lack of acceleration (NO acceleration at all for several seconds, then 1-6 MPH) after coming to a complete stop and 2) periodically when stopping at a light, the engine will start to "miss", subtly at first, then violently shaking the entire car. This can be relieved by either putting the car in park OR by turning off the AC. Of course this can never be duplicated at the dealership, though they have been very conscientious in their efforts--no complaints there. Has anyone successfully had the same/similar problem solved?


Thanks.
