ok so i have a problem some where ... because of the fuel issue ...so I have replaced my spark plugs which I paid at most i think 50 for a whole set... I have put a k&n airt filter in change my oil religiously,and oil filter have changed my fuel filter, hmmm what else do i need to look at to possibily fix this gas issue ?

I got a 2001 gls sedan with 50s stock of course and stock plugs and I get alomst 21 in mostly cummuter driving ie 15 mins of normal in town and 20 mins of bumper to bumper surface street traffic /shrug.

the tank is like 14 gallons but i swear ive never filled up past like 12.5 and the light is on E.. so idk

Well what kind of driving do you do? I used to get 18 to 20 MPG all city and I filled up and always put in between 9.5 and 11 gallons, so there is your 200, now I'm getting 19 to 21 combined city and highway since I moved to the burbs. I've been babying it the past 2 tanks and I got 21.4 and 21.6, I'm babying the 3rd right now and I have just over 1/2 tank (probably about 6 gallons empty) and I put 150 miles on the tank. That's appox 25 mpg, if I'm right. That includes a road race today and 80 on the NJ turnpike just to keep up with traffic.

With the K&N, at 65 I'm under 2000 RPMs ;)

hmmm well i have been a pretty radical driver but since my first car show last week and joining this site I have calmed down cause I have realized how stupid I look especially since I am 26 and doing it so this tank i have right now is the first tank I have been for the most part a normal driver although I have caught my self doing quick accelerations which I am trying to break that habit now

Ya, stop the hole-shots all over the place. My Alero (ecotec) can easily get at least 300/tank (usually 25 MPG) in town and i can get over 400 on the hwy.

If I drive the crap off my 3400 around town I have gotten it down to like 14 MPG or something like that (maybe less, I usually don't track that one)

hmmm ok so would my 2.4 having near 130,000 miles be part of the problem ? and at that many miles what should I be replacing inspecting,or changing ?

ya at this point the most i get from a tank with driving like a nut is like 225 so idk its a hard habbit to get rid of

isnt that the damn truth even though I know all i am doing is shaving a few seconds at the most off of my time to my destination

yup itryed driving slower tonight but more ppl kepted riding azz

Iridium plugs have less resistance, so its like throwing a hotter coil on your motor. This is why they claim 10hp, for those with weak ignitions. They are also self cleaning and last a long time. Is it worth the money? In the long run, yes. Double laser platinum? I dunno what that means but I wouldn't use platinum plugs, or anything that says bosch on my vehicle.

well mine arent bosh and from the sounds of it bosh isnt that good

^^ Please type in English

lol it was english I was just a lil or a lot sleep deprived lol

mabye ill look into it but it seems alittle expensive for what it is

w/ what mods?? i know you have an exhaust, probably a cai? anything else?


i average 25mpg, and its usually split 50/50 hwy/city. i got in the mid 30s when i was going to ASS (all highway)

if your car is high miles, you can try throwing a can of seafoam through it, see if that cleans it up and improves your mpg.

so I guess 15mpg in town isn't all that good? Maybe it has something to do with my tailpipe looking like a military-grade flame thrower (without using a spark kit).

For Iridium plugs, use the ACDelco #41-101. They're the factory original plugs for the 3400. They're made by NGK.
