Hello all,
I have a 2011 XC90 with 150,000 miles, AWD, and has the 3.2 in it. When I am driving and depress the gas pedal, basically putting some pressure or torque on the car, the engine sounds like it is pinging, scratchy, marbles, or rough, the engine runs smooth at the same time. This is very ...
