194-horsepower 3.0L V6 4-speed automatic FWD

150700 mi US $800 Replaced two Fuel Ratio Sensors. Old ones were broken, which caused misfires in Cylinders 1, 3 and 5. This mimicked significant transmission problems, dropped fuel efficiency, burned fuel in the exhaust pipes and put fuel in the oil.

198000   Stuck PCV Valve and wear fouled the spark plugs, wiring, fuel filter, fuel injectors, which created misfires and sludge build up in throttle body and intake manifold. Replaced plugs, wires, PCV valve, filter, coils boots, grommets & gaskets
