My 2nd O2 sensor is STILL bad. They just ordered the part last week so I am taking it in tomorrow to finally get fixed. Well I was wondering, is that the reason I am getting much poorer gas mileage? I just filled up today and I got 260 miles to my last gas tank of 16.4 gallons. That averages to just over 16 mpg... not good!

When I have my A/C on, does the compressor shut off above a certain RPM? I know that it can damage the compressor by flooring it with the A/C on. I want to know so that I don't demolish my compressor! Also, how long do you think that compressors last on average (made in 1995). I live in an average climate where the temp is almost always between 50 and 85, So Cal. Thanks guys.
