hi i have a l @ k 53 plate. past few weeks ive noticed a power loss when i try to over take. not a total loss of power but enough. when on the motor way its the same thing normaly i just kick it and it takes off now it takes it`s time to build up speed. had a back fire other day. any ideas before i start to get realy worried:confused: :confused: its had a major service at 100k

Which engine, and do I infer correctly that it's an automatic?

if it an automatic, check that the kickdown switch on the bottom of the accelerator pedal isn't disconnected or loose
