DRIVING, ACCELERATION, AND FUEL ECONOMY HAS DECREASED/WORSENED. A MECHANIC IN SANTA MONICA STATED THAT THE OBD READINGS SHOW RANDOM ENGINE'S CYLINDERS MISFIRES; AND A THREE-DAY PHYSICAL OBSERVATION AFTER THE INTAKE MANIFOLD REMOVAL SHOWS: UNEXPLAINED COOLANT OIL CONTAMINATION ISSUES, OIL MIXED WITH COOLANT AT EXPANSION TANK, RAW FUEL ON CYLINDERS, FUEL BLOW BY, AND REPEATED SPARK PLUGS BURNING AFTER EACH REPLACEMENT.
