Every mechanic I talk to can't believe that it has failed again. The car has always been serviced. Each mechanic has checked filters and fuel and found both to be perfect. The motor sounds as though it is being starved of fuel or that the timing is way out. There is an intermittent rattling noise with a loss of power.

At first this just happens occasionally. The car is actually driveable, so far, but the loud revving or rattling has people in the street turning to look. Has anybody come across this before?
