On mine, the epoxy backing of the bulb socket was cracked allowing water to pass. I sealed it up with silicone and all was good.

^^ this also. The mpg rating for that model was only 15 city/20 hwy. so if you do not much highway and your heavy on the pedal you are right on the money.

I don't think you have the right part number. the Bosch O2 Sensors at rockauto are only 87 each.

You could try holding the socket externally with a pair of vice grips and get the Allen wrench through the top.

The lower mileage V8s are becoming a rarity so someone will pay that price. I bought my 2010 2 years ago with 45k on the clock and it was 19k. I have put 60k on it without issue.

More likely that the parking brake shoes delaminated from the hit and are just floating around inside the rotors inner drum.

This is normal. It depends how the engines tuned also. I assume your Saab requires premium fuel which would contain more energy than regular and would even out the winter blend a little more.

Engine replacement? Looks slightly different.
