The past few weeks or so i have noticed a slight hesitation when i accelerate and today i took the car out on a long journey and its got worse, it hesitates alot more, more often than not. Sometimes it hesitates but feels like more of a jolting 2 or 3 times. Is this just a simple case of cleaning the maf or could it be something else? Im pretty sure its not the spark plugs or leads as i only changed them recently when i serviced the car.
