Thought I should share this with you. For a number of weeks my F75 has suffered from lack of power and would not do more than 60 mph. I did all the usual things....bled the fuel lines, bled the injectors, checked the fuel tanks and fuel lines...even checked all hoses to the turbo. The truck would sometimes run ok then lose power again.
3 days ago I climbed into the drivers seat and dropped my pen. I had to remove a floor mat to find it. Since then the truck has run like a dream....plenty of power...best acceleration ever and will do over 80 mph (a bit scary though). It seems the corner of the floor mat was getting trapped between the accelerator pedal and its stop !
Although I feel a bit of a fool the problem was sorted in the end and I pass this information on in case any of you have a similar problem.
