You're getting 47mpg at 80mph!? Wow. And this is with the new $79 o2 sensor?

Gary, I haven't installed it yet. Might do it this weekend.

Yes, I get 47mpg on my 1600 miles ride with an average speed of 80mpg

Alain, now that it has been some time since you installed the o2 sensor, is everything you said here still true?

Also, what kind of mileage are you getting at normal speeds? (not 80mph!)

Sinse I install my new sensor, the car still run as a new. No more vivration, no more bug down.

I should have change the sensor before!

For my MPG at normal speed, I will let you know when my tank will be empty.

the only wrench I have that will fit the o2 sensor nut is an adjustable wrench. I sprayed it with PB Blaster, so we'll see if I can loosen it tomorrow. Was it pretty hard to loosen yours?

Go pick up an 02 sensor socket for 8 bucks at the auto store.

Drive the car on the highway in lean burn for about 30 minutes. Take off the heat shield from the manifold before you go on that trip though. When you pull into the driveway, pop the hood, grab your wrench and then give her hell, and she'll turn like she was soaking in lard! BTW, a 7/8th open ended wrench will work as well, or a 22mm or 23mm wrench.
