what is a MB booster?

it occured to me to check the 02 sensor. I keep a book of every gas fill up I have ever put in my car. last two fillups are 22 and 23 mpg.

some more info on my situation.. my poor gas mileage happened almost immediately after I replaced my ignition coil, cap rotor and plugs. Like I said they use to be.060 inches and now the new plugs are at .040 (factory)

I was going to check for any codes the car might throw....asiandood, how do I get to that two prong connector? i looked and looked but I couldn't find it?

what SHOULD the residue on the o2 sensor look like when I remove it?

the air fuel mixture is controled by the ECU right? there is no way to manually adjust the air/fuel on a stock engine?

no more draggin on brakes... what else?
1) Bend over

2) Remove the lead foot

3) Instantly gain better gas mileage.

Also as the colder weather sets in air is denser so it contains more oxygen. More oxygen requires more fuel.

Did you check your tire pressure as well? Don't know if that was brought up, I didn't read the previous posts...
