I just picked up a 2001 Xplorer with about 500 miles on it. The previous owner wasn't exactly sure on the mileage, but said he thought they had gone through about 4-5 tanks of gas.
At low RPMS, the engine makes a consistent noise. Not sure if I would describe it as a ping or a knock. Don't think it is piston slap, but not sure. It sounds like it is coming from the cylinder area. When you are riding at slow speeds, the noise persists. When you get the RPM's up, the noise disappears. Does anyone have any idea as to what I should look at to solve this problem or is this normal? Looking for some direction.
