Consumer Description

I EXPERIENCE AN INTERMITTENT PROBLEM WITH MY TRUCK THAT FLASHES AN ERROR CODE "REDUCED ENGINE POWER". THIS IS TIED TO ERROR CODE P1516. USUALLY THIS PROBLEM OCCURS IN COLDER PARTS OF THE YEAR, AND ON A COLD SOAKED ENGINE, BUT IT HAS HAPPENED OTHER TIMES AS WELL. AS SOON AS THE ERROR OCCURS THE THROTTLE SHUTS AND LEAVES THE VEHICLE WITH ONLY INERTIA TO ATTEMPT TO GET OFF THE ROAD. THIS HAS HAPPENED TO ME ON THE INTERSTATE, AND THOUGH I HAVE NOT HAD AN ACCIDENT YET, I DO CONSIDER IT DANGEROUS. I HAVE TAKEN THE VEHICLE TO MY LOCAL DEALER AND INDEPENDENT MECHANICS, AND THEY HAVE BEEN UNABLE TO RESOLVE THE PROBLEM. THIS SEEMS TO BE A WIDESPREAD PROBLEM WITHOUT A SOLUTION. *TR
