Hey Guys:

I have a 97 Accord LX (2.2L, auto) with 60,300 miles. My MPG per fill-up (13 gallons) is HORRIBLE. I’m averaging ONLY 14 miles per gallon city. HORRIBLE for a 2.2L 4-banger. I’m trying to figure out why the mpg is so bad.

I’m the 3 owner of this car. I’m not sure what type of maintenance the other guys did. I just did a tune up (plug wires, NKG plugs, fuel filter, distributor cap etc). I haven’t done the timing-set yet...soon. While the car was getting a tune up, I noticed the muffler was completed dead – it was rotten and almost disconnected from the rest of the system. I’ve tried all 3 grades of fuel and the result was the same. I even drove “easy” after 1 fill-up and got the same result.

Furthermore, not only is city mpg bad but also highway. I went on a little highway trip this morning. 60 miles and almost quarter of a tank was used. I averaged about 65-75 miles per hour speed.

Does anyone have any idea as to this problem? What else can in do? I KNOW the MPG should be a better.

Thanks in advance.
Damian

 

air filter, blockage in the air inlet tube, exhaust blockage, bad cat, fuel pressure regulator dumping fuel, ERG valve, transmission faulty, e-brake adjusted too tight, bad master cylinder keeping slight pressure on the brakes, low tire pressure, very bad alignment. Stop now or carry on??

There are tons of things related to poor mileage. I have not even tapped into the ECM part yet. $$$ OBD II scanner

 

if it has 60k

it cant be a ton of things

if your car is stock you should go with original parts!

did you get bad mileage after or before the tune up?

you should get your whole exhaust checked out if its has holes
