Consumer Description

VEHICLE WAS IDLING POORLY, IT HAD A ROUGH IDLE THAT WOULD SHAKE THE VEHICLE. THIS CAME AND WENT, IT WAS NOT A CONSTANT PROBLEM BUT SLOWLY GREW WORSE. IT WAS DIAGNOSED THAT 4 OF THE EIGHT CYLINDERS, ONE ENTIRE BANK, WAS MISFIRING. THE TROUBLE WAS CAUSED BY A FAULTY OXYGEN SENSOR THAT WAS DUMPING 50% MORE FUEL THAN NEEDED INTO THESE CYLINDERS. THE SENSOR WAS REPLACED AS WAS THE SPARK PLUGS WHICH HAD BECOME FOULED. *NM
