My wife's '05 MCS convertible automatic has just been towed to the dealer for the second time. While driving, the check engine light came on and then the EML light came on and then the car wouldn't accelerate over 15mph. the first time they replaced a sensor in the super charger and said it was fixed, this time they replaced the sensor and said they had installed a new software program. I have heard that this is a common problem with the MCS automatics. Anybody else out there having this problem? By the way both of my '05 convertibles have the wonderful stall problem when you start them as mentioned elsewhere on this forum. Thanks Darryl
