I just did some calculation today after using a fuel system cleaner to improve fuel economy and this fucking piece of shit 4 cylinder car dropped to 17mpg!!! I going to trade this shit in for a civic ex or just stripp it to pieaces and sell the parts.....I did EVERYTHING possible to try to fix this gas mileage problem ...the dealer...full tune up......fuel unjector flush......NOTHIN!! by far this is the WORST fucking car I ever owned.!!

 

Did you change the fuel filter? Also, is your car runnig rich? Has it been tuned? What about timing? Sorry to hear you're still having so much trouble

 

yea man. Sorry to hear you're still having so many problems with the gas.

Good luck with your next car, and if its a civic, that thing should be pushing high 20's in gas, no problem.

and high 20's on the track too

 

so true

 

I can get a good 400 miles from a full tank on my 99 2.3 CL, which of course is mostly highway miles.

 

 

highest mostly highway miles I got out of my 2.2 was 380ish.

I'm averaging about 320-330 with city miles mixed in.

 

I get 380-400 in my 3.0

by your 4 banger

 

every car has its problems, even the best car in the world can have problem, u need to located the problem and fix it, i kno its not much advice but the CL is much better then a civic

 

meh. I havent taken my 4 banger in for a tune up in a long time. I pulled 380 just a couple weeks ago.

 

most I got from doing just hwy is 360 FUUUUUCK!!!! I HATE THIS FUCKING CAR!!!

 

try some seafoam

 

there could be a problem with a sensor, but it's not throwing a code becuase it's still in its range of operation

example: in an older car I had, I got SHITTY gas milage. I did everything, tune up, fuel filter, you name it. i scanned the computer for codes and got nothing. i ended up picking up the service manual and did some reading. i broke out my voltmeter and checked the voltage on the few sensors.

it turned out my temp coolant sensor was TOAST. when the engine was cold, the anti-freeze is cold too so the ecu makes the car run rich. when the engine warms up and thermostat opens, the sensor reads the temp of the hot coolant and tells the ecu to start leaning out the air/ fuel ratio - and thus getting better milage

the sensor didn't throw a code becuase it was still working (just not properly, was reading cold coolant no matter what, so it was sending a signal to the ecu - but the wrong one).

i changed the temp coolant sensor and was amazed at the fuel economy I got

i'm not saying that your temp sensor is gone, but it doesn't hurt to get it and like your oxygen sensor checked out as well
