Last day of the Kentucky road trip, and we have a very neat car to diagnose!

This 1990 Jaguar XJS has the big V12 under the hood.
Owner says that the IDLE speed is way too high, and it SURGES as the engine is warming up.

Also, one of the rear quarter power windows is stuck down, so cruising around in bad weather is problematic.

Let's see if we can figure out these quirks NPR-style, and take the BIG CAT for a spin around the block :)

Enjoy!
