Default What's up with my gas mileage..

I'm wondering why my engine is eating so much gas so, i decided to full her up and reset the trip meter. I got about 300 miles (25) combined. Weird i should be getting around
MPG (city) 39
MPG (highway) 45
MPG (combined) 41
what in the world could be wrong with my engine?

spark plugs?
wires?
dizzy cap?
air cleaner?
oil?
o2 sensors?

is your cat clogged?
are you driving it hard?
are you driving it too much like a grandma and bogging?
im not sure where you are, but are you still running a/c?(if you have it)
are your tires inflated properly?
hows your suspension?

I shift around 2500 to 3000. Tires are perfect, i check every week. cat is clean. i don't use the a/c much.(5 mins a day) suspension is stock. Oil is new. Spark plugs, dizzy cap, wires all changed in march. I basically just got a tune up in march.

i had some gas mileage issues about a month ago...
ended up being my o2 sensors.
i changed everything anyway...

what kinda spark plugs and wires are you using?
if they are cheapies, buy new oem wires from honda and some ngk plugs.

o2 sensors are easy...
not the cheapest, but they are an easy fix.

definitely worth it if you get 10mpg more than you are right now...


do you know the difference in exhaust smells?
rich vs. lean vs. normal?

if you do, smell your exhaust at idle when its up to operation temp.
thats one of the easier ways to tell if you may need to run a diagnostic on it and see where youre running air/fuel wise...
