Please help me! I have a Volkswagen Polo 1L 1999, the car is not running right, it does not seem to accelerate very well... foot to the floor and its struggling to do 40mph. It starts first time every time and the problems seem to occur when the car is hot and only when i am accelerating! It makes a very strange noise like its misfiring..it almost sounds like a tractor. My dad has checked the spark plugs and they are clean and sparking. If anyone has any ideas as to what it can be please help!!

dont rule out the plugs just because they are firing for what they cost to replace too replace the plugs and see how the car is then also check air filter too as any restrictions can effect the car perfomance
