Hi guys,

Q1: I just wondered, is it normal for the gas mileage to vary so much between city and open road measurements? I get a poor 13 mpg in the city and over 20 mpg when on open road!

Q2: Can a hole in the exhaust system (near the catalythic converter) interfere with the operation of the O2 sensor? I think I noticed lower performance and gas mileage since a hole developed there!

Thanks in advance!
