Since I've first posted this thread, I've had to replace the rear axle bearings, rotors all around, add more refrigerant to the A/C, learned to NOT use 75W-90 in the rear (must use 75W-140), and replaced original radiator hoses and thermostat (pre-emptive, not required). Has anybody ever done an engine flush? If so, what differences did you see? I've moved to the high mileage oil as well. Engine/car has 154,500 miles on it now.
Oh, starting today it threw O2 sensor trouble codes, for both sides at the same time! I find it hard to believe both upstream sensors are going bad at exactly the same time.
