- A bad oxygen sensor might give you a funny idle on top of
- other things. It's departure should be gradual. What will
- a dead one do? I don't know...nothing for your EFI efficiency.
-
- Don't forget that cold weather will take a real toll on mpg.
- Oxygenated gas just makes that toll a little more ridiculous.
- Why this stuff is introduced during the winter time without
- warning makes me suspect that someone is trying to hide something.
- You won't hide it well in California. But you'd still make a
- big profit $$$. Now, why didn't I think of this...

- Assume that everything is well-tuned and well-maintained,
- you can isolate these flying dutchmen by knowing how well
- your car usually runs in given conditions.
