Gas Mileage

[bu-bye]

does the MAF screen make a big difference in MPG? I took mine out a long time ago and did notice anything. Today I'm getting 19mpg in the city and almost 22 on the HW. Those numbers stink. I replaced the wires and plugs but no dice.

Ok then something is definately wrong with mine. I'm not sure of my mileage but I get around 160-170 miles on an entire tank. Now THAT sucks. However it almost all city driving.

I changed my plugs and noticed a little dif but not much. I'm on a 3.4, what else could it be?

Thats me too. And I am a 3.8! I don't know what is wrong with our cars...

Oh, check things like ya plugs, wires, tire pressure, PCV, exhaust set-up and so forth. I can't remember who, but a guy just posted some numbers about his MPG and it's aroung 32. You may get some additional info on how he accomplished it.

fuel filter, thermo, air filter etc. couldn't agree w/ you more.

Its all a matter of being tuned up well.

Last time I drove my car last year, i was getting about 30 mpg, with 70/30 Highway/City. This was just a Catback and CAI.

After I put in my headers, new plugs and wires, I think I should see nearly 32-33 doing 70/30.

Just do all the basics. Do a full tune up, new fuel filter, clean or change your air filter(s), make sure all your tires are inflated right, ect.

The biggest key to gas mileage is just basic maintenance.

My friend has a ThunderBird(supercharged) gets about 14mpg in city, fills it up every week, so i think you guys are pretty lucky unlike some folks with there big @$$ suvs and what not.

I got 23MPG when my car was stock, 60/40 hwy/city. Now I get 24.5-25.0 on average.

Plug back in your IAT sensor if you did the resistor mod. With the mod, I lost about 3-4mpg in my 93. Also, check your O2 sensors. I jumped from about 20(mostly city) to 25 with the resistor in [img]graemlins/banana.gif[/img] . Another thing is to check your transmission and differential oils. If they are bad your milage will go down.

Hope this helps. :D

I'll say it again... A4 guys, make sure that TCC is locking up!

i get about 22-25 50/50 and i jsut have my MAF screen out and no cat so i'm no complaining but gas prices just dropped here so ya

I get about 350 per tank 70/30 hwy/city but in Ct. It is all city no matter what road you are on [img]smile.gif[/img] it has gone down a little bit latley but not much I would deffinantly do a full tune up on the cars that are getting the crap MPG.

I get about 28-29 traveling back and forth from Norfolk to my home town Spotsylvania/Fredericksburg. I think the worst I've ever gotten was like 17ish when I did a lot of city driving and stoplight racing [img]smile.gif[/img]

I'm all stock and I've gotten up to 390 per tank on just regular - non trip driving. Last tune up was a month ago and I was 3K miles overdue on my oilchange. I was running 89 Octane and Seafoam throught it though aswell to achieve this.

On average I get about 340 miles per tank with normal fillups although it's starting to decrease and I don't know why... tires are inflated and everything and the car has been running a tad bit strange lately too.

DEFINATELY put your MAF back on if you're a 98 and below... It tells the computer how much air is being sent into the car and the computer in turn controls how much fuel is sent to the engine. If the computer can't get a reading of how much air it's getting, it's just ganna go balls to the walls and with your gas and swollow it all up just to make sure your car keeps running. You're probably running hella rich!

when i first got my car i got about 220 between fillups. for the last year i have gotten 200 or 15.5mpg between fillups. i stopped gunning it on the last couple of tanks and on the last tank i got 19.1mpg and about 265 miles and i dont enen remember the last time that i had a tune up and i believe the origional cat is still on it.
