SOUND LIKE YOUR ENGINE IS PINGING (SOUNDS LIKE A BUNCH OF MARBLES IN THE CYLINDER). THE SYMPTOMS INCLUDE LOUD NOISE, ESPECIALLY UP HILL AND LOSS OF POWER. PINGING CAN BE THE RESULT OF MANY DIFFERENT THINGS INCLUDING: LACK OF FUEL, INCORRECT IGNITION TIMMING. WHAT TYPE OF VEHICLE IS THIS (YEAR, MAKE ,MODEL) AND HOW MANY MILES?
