Horrible Gas Mileage

Horrible Gas Mileage
I know this has been talked about before in the sense that some people's Maximas get horrible gas mileage. But I'm a little concerned about my own mileage numbers.
I just recently purchased a 2001 gle and have been getting only about 200 miles on a full tank of gas. That roughly equates out to about 14mpg. Does that sound correct? Is there potentially something wrong with the car? Is a sensor messed up and is injecting too much fuel?????
It's kinda freaking me out...

Try to find some info in the other gas mileage threads that have been started in the last few weeks....

I get 22-23mpg all the time...mix of highway, city, and bumper-to-bumper...but I also have a roof rack, which knocks a few mpg off I'm sure...
Best I've ever gotten was 27mpg, with my roof rack taken off and long-distance highway cruising
14 is WAAAYYYY low though. Even when I have done all city/bumper2bumper driving on a tank, I never have gotten worse than 20mph.....Definitely have it checked out. Also might want to try some Seafoam to clean your intake manifold and some BG products in the gas tank....might help out some by cleaning out whatever gunk you have in there....

Whats the tempurature like where you are? That plays a big factor. Í used to get 650+ km (I'm in Canada) per tan before getting a gas light. Now I'm about 480km. Same with my buddies 00 I30T, same VQ motor...So weather does play a big factor to.

First of all, thanks to everyone who posted a reply!
Granted, my driving is mostly city, but I think 14 mpg is still a bit low
Thanks for the advice irish! In terms of the seafoam and cleaning the intake manifold, do you mean that procedure where I suck seafoam down the brake line vacuum? Also, I've never heard of BG products. What are they, what do they do and where can I get them?
The weather here in Omaha has been fairly cold lately, but has been above freezing for the past week, I'd say, for the most part (except at night), but I don't seem to drive the maxima too much at that time.

that is way too low....
my 00 se still gets 20mpg and it has been around 3 deg. up here the last two weeks. it also depends on how much you let your car warm up... if you let it sit and run for 10 min.... that is not gonna help.
i would check your air filter, i have a K&N filter, works great...
till i get my Injen CAI....

I get somewhere close to 15-16mpg in the winter..this is with city driving with no more than 6 miles drivin everyday(work is onyl 5 minutes away)!! I get somewhere between 20-22 in the summer with the same type of driving ( 5 minute drive to work)..on the highway, i have infact hit 32mpg this is with no a/c on and driving for 15 hours continously.

Does the car have power ? Does it run very smooth when trying to accelerate to redline ? I would suspect the MAF being a culprit here as its one of THE major Air fuel ratio inputs to the ECU.
BG products can be located through their website, by looking up a autorized BG dealer. I just lucked out that my old Acura dealer I used to work at was using BG so I stacked up on BG44K and put it in my tank every 15K miles or so. I'm not using SeaFoam, I tried it and it didn't clean the intake manifold at all. BG Induction cleaner works like a charm.

mine gave 15 and it went to 22 after coils, plugs and maf change. can't say which one fixed the problem. the money i save with the increase of mileage, paid for the mentioned parts..

i just did seafoam on my 2k and put an entire can into the gas tank thanks to advice from "Cuello" at O'Reilly. i have been getting between 16-19 city/highway. I recently got the coil code but didnt replace any because it couldnt be determined which one was acting up after them all being tested on an ohmmeter. i have also had some rough idles when i start the car at different times and while en route somewhere. i didnt get too much smoke when doing the maxima but when i did my old 96 altima w/ 124k it smoked like a ****. i'll report my mpg at next fill up. oh and 3 different people told me NOT to put ANY into my oil...has any1 done so and gotten bad results?

I've noticed an engine noise that I think is a bit weird that I'm going to start a new thread on. I don't quite know if it's related to the poor gas mileage.
