I have recently noticed my MC 2003 stumbling under accelleration, more so when cold, if I boot the gas pedal and keep the revs above 3500 it runs better, is there a cure? :sad:

I've experienced the same problem with my 2002 MCS after updating to the latest software version. I've also heard reports of a surging between 3-4K rpm that may be related. Be sure to check in the Beneath the Bonnet forum for associated information.

Mark :grin:

what cars should get the latest software update?

i have a november 2002 build 2003 mcs and have no problems
