fuel filter or fuel pump problem ?
Yesterday while I was driving I noticed that when my car reached 5000 rpm the power began to surge. Before it reved freely to 7000 rpm now between 5000 and 7000 it starts to hesitate as if one moment it has enough fuel and the other it doesn't have enough. I had it up to 190 km/h and there is no hesitation if it's below 5000 rpm. Could the problem be a clogged fuel filter or is the fuel pump ?
