How's it feel to taste your own medicine?

Can anyone post more info on this O2 testing stuff? I replaced one of mine recently because of a check engine light reading, but I'm still getting like 17-18 mpg in the city (22 AT BEST on the highway). I bought an RMS multimeter a few weeks ago, so is this something I can use to test my sensors?

That mpg range is fairly normal for both the 300 and 400 so aside from being gentler off the line, there's not too much more that can be done to improve it.

Oh, and I had my O2 sensors go bad throwing me the Check Engine light. So I replaced them with brand new geniune OEM sensors and there was no improvement to my fuel economy.

Haven't gotten a good test since I replaced my spark plugs about 4 months ago, but last time I did get a good test I got right around 27 on the highway. Seems the secret to getting mileage in the SC is:

Don't use the AC (no problem now that it's cold), sweat to death in the summer instead;
Accelerate like you have an egg under the gas pedal.

Only thing not factory on my engine is the K&N cone filter the previous owner put on. I seriously doubt that's giving me that much extra mileage. This car just has so much heft there is no good way to get good city mileage, which is where I assume all of you are driving. And as with any car, shut it off if you're gonna have to idle, and use the brakes as little as possible, that's a little easier for me though, cuz I have a 5-spd and can go into no-gas mode when I coast. I've gotten just about all of the lights in my area down, so it's a lot easier to predict when they're going to change and whatnot, makes it easier to coast down, or not slow down at all.

Summation: If you're driving in the city, drive something else =) I've taken to biking everywhere I need to go, cuz I can't afford the city mileage any more!

I went from a Camry to this car. Obviously there is a difference... but I would spend the extra on gas to keep drving this car vs a Camry haha
