Q: My car is difficult to accelerate after running for sometime

asked by on October 27, 2016

Am using Mercedes Benz Atego 817. You can ran it for sometimes , let say 20 minutes then you leg will be on the padel fully pressed but it will not accelerate and sometimes the engine will go off and starting it again becomes difficult. When you are able to start it again you can't move it unless you wait for sometime. What could the problem be, because they have made me change the injectors and fuel pump but still the problem persist.

My car has 120 miles.
My car has a manual transmission.
