Hiya, I have a Mercesdes a 140 elegance, since a few weeks ago i've noticed that there is a lost of power and the car also hesitates when I press the gas pedal. Its does consumes a lot of fuel too. I have done a fuel servicing ( air filter, fuel filter, oil filter, pollen filter, oil and sparks plug) hoping to clear the problem. Can u advise me the next steps. Thank you
