Motor threw a rod. Since it is somewhat a "rare" model, I opted to have the motor replaced or rebuilt just like the factory motor. It is not a common motor so they couldn't find a replacement that they would warranty, so they sent the motor to Jasper Engines to be rebuilt. It has come back, but I still not have it back yet. I expect to have it in this week. The oil level had dropped too low and that is why it threw a rod. No leaks, unclear how the oil level got too low. Sometimes when I started it up, it would smoke initially, then it seemed fine. I'm having them install a real oil pressure gauge as well.

32200 mi US $258	On-going engine pulsing/misfire at cruising speeds which turned into engine surging up to 3000rpm randomly. Diagnosis by shop determined Throttle Position Sensor was failing.
35000 mi US $50	After replacing the Throttle Position Sensor, there was still a slight misfire and mileage still seemed poor. The plugs and wires were replaced and the misfire seemed much better plus the mileage improved. There is still a slight "lag".
