For the last year or so the gas mileage on my wife's 2000 Civic has been getting progressively worse. She is doing the same type of driving, does not idle it all that much anymore, but yet her MPG this last tank was 20.5, compared to 25-26 at this time last year in similar weather. It's actually been warmer lately too, but yet the last few weeks the MPG has gone steadily down each tank.
I'm going to be getting her trans fluid changed tomorrow and figure I'll get the fuel filter done too while I'm there. The car has 40k on it and neither of those two things have been done yet.
The thing is, the car runs great, doesn't feel down on power, and when I changed the plugs last week they looked fine, it didn't look like the car was running rich at all.
I'm stumped as to how a car can get bad gas mileage without running rich. I even did most of the driving in the car over the last week and while I did do all city driving, I definitely didn't idle it too much and it's definitely getting terrible mileage.
