Rough Idle, Gen2 V8

[dunndarryn]

This is crazy, I have the same problem with my gen. 1 but never really thought anything of it. I have a slight vibration sometimes at idle. Other times, it idles so smoothly you can't even tell the car is on.

In Florida, there's barely such a thing as cold but (in my personal case) I have come to find that my car seems to run better the cooler the weather.

Most all cars (Ford in particular) run better in cold weather. Cold air is denser, so it is possible to get more air in the engine and power out of the engine.
