hi guys i got 120k miles on my car and im getting 17.5 mpg i wanted to know what the best thing to do to help improve mpgs besides driving slower like what can i change to help improve this and get it to where its sapouse to be like 23 mpgs
what does that mean?A/C and windows up after 40mph. no A/C and windows down less than 40mph.
You're running rich. Are all the trips you take short ones? EDIT: also, are you feathering the throttle until the engine is warm?I think my driving habit is not bad, i rarely rev over 3-3.5k rpm and i know how much you lose everytime you step on brake.
This morning, i spent awhile check all 6 spark plugs and i found most of them were wet of gas and oil ( i guess). I think this is why my fuel efficiency is so bad, too much gas were injected. i heard other thread was saying this type of plugs last at least 100k miles, mine just turn to 58k, so i brushed clean with steel brush and air down and put them back, i hope poor mpg is not from these plugs. I had changed air filter last summer when it has 52k and i double checked it was not dirty. I don't know about fuel filter, i may want to change it later. I dont know about O2 or vacuum leak. i dont get error code other than po365, also misfire
And i also checked exhaust camshaft sensor, it wasn't so hard to take out. I am getting one from

it's just 31.59 with o ring plus 8 dlls shipping, is this reliable one..??? price is not bad though...
I will post the result after i replace cps, I hope this is the main cause of poor mpg...
thx,
My Honda winter car failed emissions because it had a sticking front caliper.. go figureTHANKS YOUR HINT ON BRAKES,
I DID NOTICED A BURNING SMELL ON THE WHEELS AFTER ROUTINE DRIVE FROM OMY WORK ABOUT 10 MILES OR LESS. I HAD REPLACED REAR BRAKE PAD RECENTLY AND IT MIGHT BE ONE OF THE CAUSES....
AC_2007,
What do you mean by " feathering the throttle until the engine is warm" ???

Does anyone knows this auto parts ebayer ??? or any other recommendations.....
I am appreciated....
:thumbsup:
You might be missing that IF the K&N flows more air, your ECM will inject more fuel to compensate and keep the Air/Fuel ratio the same and decrease your mileage......I am driving all week to make sure my MPG smooths out before installing it so I can determine the effect. Personally, I don't think the different air filter could have that big of an effect. Maybe I am missing something??
