I have a 2008 V6 Pony Mustang with an acceleration problem. The motor misfires under hard acceleration and Ford knows that the fuel pump does not pump enough fuel to keep up with the engines need. I have talked with my mechanic and several other owners with the same problem. I took my car in for a warranty check long ago and Ford said they couldn't see any problem. There is a problem when the PO300 code keeps popping up. I wish Ford would fix this problem. This can be dangerous when passing other cars.
