94 Accord sudden mileage drop
 

I have a '94 accord 4-door with 145000 miles. The car runs
absolutely great, but recently the mileage has gone down
10-15% (from 28 city to 24, 33 highway to 29). I've verified
this over several tankfuls. There's no noticeable difference
in performance, acceleration, engine smoothness, etc. Nothing
appears to have changed except the mileage.

Anyone have any suggestions on what to look for?

TIA

Clean air filter,proper tire inflation,clogged catalytic converter or
muffler? Maybe auto transmission problems; Worn torque converter,slipping
bands? How's the motor compression test?
Are you using the same gas,or has that 'oxygenated' gas hit your area?
Driving more in heavier city traffic,more stop N go?

Check your records--it may be time for a tune-up. During a tune-up, the
engine is connected to a huge computerized tester and the mechanic should
be able to identify any problems with your Accord.
