Took it back to the dealer who claims all's well with the car. They ran the codes, twice (Heaven forbid a mechanic might actually pick up a friggin wrench anymore). I ahd considered pulling the plugs this coming weekend and maybe run a leak-down test on the cylinders. At this point, I need to remember that it's a lease, the term on the car is almost up, and Iv'e done my due dilligence by reporting the problem to the dealer and letting them examine it for all-clear.

I hope it is all-clear for the next person who owns it.
