Chuck,

Again, Thank you for responding.

When the car is completely cold it starts immediately. The difficulty in restarting is when the engine is warm. The longer it sits, the easier it is to start.

The poor mileage occurs even at lower elevations (100 to 400 feet) so I'm not sure it would be the O2 sensor.

I will do a search to learn about the on-off ratio.

Thank you again!

Tim
