wow thats weird, i get like 27-29 on the highway. are u going by what that little on board comp is telling u? those are never really accurate.

You need to reset the MPG meter. If it has not been reset in a long time, it is calculating the average, so it will not go up much without a lot of constant driving.
What I do is when I am on the highway, I reset it.

Lucky. I'm getting about 12 mpg city. The DIC says 16, but that's bull****.Originally Posted by a98gtp4u

well bensett, you could always just trade me gtps. i get 28 highway

when i finally got my car tuned to get more timing when cruising i got 26mpg when i ran straight highway, but i normally would get 21/22 mpg with a mix of both.

Mine shows my average and then shows what im getting right then and there! Its around 20-27 or when im going down a hill 99.9 or when im going up a hill 3.2!

mpg has alot to do with driving technics
10-20-2009
i would say you need to pull the battery... and wait 10 mins.. then go for a drive and take it easy no gasing it. That will let the computer learn,...
I got 8mpg with some AP103... Usually i get 18-19 city without air and around 30 or so on hwy..

Used to get 23mpg (even when mashing the gas) with fuel logs & port. Getting 18mpg on stock rails now >_<

i have done the battery thing,and i have reset it, and thats what im going off the digital thing, i drive good, i mean once in awhile i get on it but not alot, when i went on that drive, i set the cruise at like 73....just dosent make sense, i am about to get a dhp power tuner so maybe that will help

Well, you are right, you are getting pretty low gas mileage. Consider the fact I don’t know much about your car, except the mods you listed. I’ll start off by saying, those wheels on your avatar don’t appear to be stock size. And if the tire OD is off, so will DIC mpg. Now on to some tips, because no one so far has given even one! Lol
1) New spark plugs
I’d go with AL606 plugs. Going to an unnecessarily colder plug can hurt your mpg.
2) Clean your MAF
3) Replace your O2 sensor (if your over 100K)
The accuracy of the exhaust manifold sensor O2 sensor is critical in getting good mpg.
4) Run your tire pressure about 32-33 psi
When you unplug the battery for sensor replacement/cleaning, your car will re-learn and then you should be good.
Also, since I see you just posted again. Mpg isn’t magic, it has a lot to do with plain facts. How fast are you going with how fast your engine is turning. No car gets its best mpg at 73mph, try 68mph and see what you get.

and you had 3.29's
10-20-2009
I have a major vac leak, would that be causing my mpg to drop alot?
10-20-2009
for sure. if i had 2.93s it would have been even better. you need to run more timing when youre cruising to get good MPG.
yes.

tire pressure on the tires say 51...and how do i clean the maf? also i dont think i have 02 sensors, but there is no service light, well there is but not for that, it says egr flow insuficent? what does that mean?
10-20-2009
i can get the same mpg at 80 that i can at 60. i dont think that matters.
does the older models not tell you instant gas econemy??? that helps alot with trying to save gas. the way you drive it has ALOT to do with it also. you may think your taking it easy, but you could do better im sure.

Cars are most efficient at 80 km/h last I heard...

You can buy spray MAF cleaner in a can and clean it. Take it off the engine to clean.
Every car has O2 sensors... No code does not mean they are getting weak. You would change out the first, or front sensor.
Your EGR will also mess with things, get that fixed. You can also clean EGRs before replacing.
