2002 CHEVROLET AVALANCHE 2500 BEGAN EXPERIENCEING INTERMITTENT ENGINE STALLING WHILE DRIIVING AT APPROXIMATELY 38,000 MILES. CONDITION WAS SPORADIC BUT CONTINUED GETTING MORE AND MORE FREQUENT UNTIL VEHICLE WOULD NOT RESTART ON JUNE 24, 2005 WITH 55,000 MILES ON THE ODOMETER. CONDITION STORED NO CODES ON THE PCM AND WAS NOT 100% REPEATABLE. CONDITION IS THE RESULT OF A FAULTY CRANKSHAFT POSITION SENSOR WHICH IS KNOWN TO GM AND IS PARTICULAR TO 2002 VEHICLES EQUIPPED WITH THE 8.1 LITER VORTEC V8 ENGINE. THIS CONDITION IS DANGEROUS DUE TO DRAMATICALLY REDUCED STEERING CONTROL AND BRAKING POWER WHEN THE STALL OCCURS. SOMEONE IS GOING TO GET KILLED AS MORE OF THESE VEHICLES REACH HIGHER MILEAGE !! SHERWOOD CHEVROLET REPLACED SENSOR ON 6/27/2005 AT A COST OF ROUGHLY $200.00
