Oh, and I'm the original owner, picked her up with 55 miles on the odo. She's an MT, I beat on her everyday and she takes it in stride, begs for more even.
I'd recommend sticking it out, a couple of sensors really isn't a big deal, he'll it could've been because it was sitting too long even. When you get it back take the car on a nice long road trip (around 1000 miles) and hope that it clears everything out.
Most of my miles are highway, cruising at 75-80. These engines will give a nice 200k miles if treated properly.
