I thought the 02 has a 18 gallon tank, and FOR THE LAST TIME YESSSSSSSSSSSSSSSSSSSSSSSSS I AM CALCULATING IT CORRECT THATS NOT THE DAMN ISSUE!!

 

Im not shooting nothing back in no ones face, but when someones gives me a stupid suggestion such as, trade it in, or just replace everything, wat am i supposed to say, im not looking for someone to fix my car "via keyboard" but rather someone to say, ok it sounds like this is the problem, or a MPG loss can be either this or that, I mean it can only be so many things that cause a loss in MPG, im simply desperate for someone to give me educated answers, not smartass comments like trade it in or buy a prius, or hey, just replace it like as if that should be the problem, obviously if that throttle code never came back then its NOT an issue, but u wanna tell em just replace it? cmon now, i know im annoying but jeez dont tell me useless info..

 

BTW, the lockup torque converter, is it just when the RPM needle drops a little? looks sorta like a shift but u dont feel it and it just drops a little? if so i think ive seen that before...

 

Keep the car but stop driving it?

 

i need it for work, once again with a smartass comment a BEAUTIFUL waste of posting.. anyone with something USEFUL to say should say it, otherwise just shutup, seriously...

 

and then u wonder why i keep post whoring, cuz only 1 out of 10 people who reply here are actually helping, the rest are just flaming and being plain out idiots and smartasses cuz they have nothing better to do.

 

Here is my take on the torque converter....

i start my car... drive my light pressure on the gas pedal... rpms go up... say to about 1700... n drop... thats shift 1... then same thing happens again at around the 1800 rpm mark... at about 40 or 45mph on a flat road.. or max 50mph you will feel another rpm drop ... thus if you totally count you should see the rpms drop 4 times... and then driving at 50mph with light gas pedal pressure you will be at about 1700-1800 rpm and at 60 mph with light/medium gas pedal pressure you whould be at 2000 or a little more than that....

if you press the OD switch off on your transmission you will notice the od off light on the dash and then at 60mph your rpms will be higher than 2000. this is a very easy test that your torque converter is working fine.

Here is another thing you can try... find a gas station very close to an interstate exit. fill the gas tank full... now reset your trip meter... drive the car only on interstate for atleast 50-60 miles... now plan your trip in such as way that you are going 30 miles up take an exit and come back to that same gas station... fill your tank up again.. report your gas mileage... also do this interstate test after hours when you can MAINTAIN 65-70... do not exceed 70 and dont go below 60 for the entire trip.

as i mentioned before.. i have an 01 and my in city mpg is around the 15-16 mark... but my highway driving goes to about 26-28

I'll wait for your report.

 

Everything is in this thread already...

Re-read it with a pen and paper, make a list and start checking them off.

If you go through it all and you still get the same milage... Guess I was right.

BTW, I am NOT saying replace it all, just make sure they are working properly and some things you are better off just replacing.

IF you have questions on replacing/checking an item... SEARCH, do not post another thread! Also, go buy a Full Service Manual for your car (please don't ask where to buy one... Use your head).

 

If you consider 200+ posts and 7 pages of suggestions "useless" info, then you must not have anything to learn from those whom are offering assistance (including myself). I'll offer one more suggestion which you will probably deem "useless". How about replacing the fuel filter? Given that one any thought?

 

FINALLY something usufuel, thanks bro, ima count the shifts next time on a flat road and see if i feel that final little drop, BTW where the hell is this OD switch? I see everyone talking about it but I have no clue where it is, turning it off will make the MPG worse correct? but at 60MPH my RPMS are always a little higher at 60MPH im usually at about 2200 rpms or 2150ish... keep in mind i have an 02 so its a different engine... i dunno if that makes a difference just figured id let u know if u didnt already lol..

 

na i never said everything was useless im saying alot of stuff people are saying are stupid comments and u know this urself.. yea i always gave that a thought but do u think in my year being that its IN TANK is it worth it and will i possibly see a difference or those dont usually go bad? only reason i ask this is becuz i just dont wanna replace it for no reason u know?

 

Yeah...we know it's in the tank. And we know you're '02 has a different motor than the '00-'01's. The fuel filter will probably be one of the less expensive replacement parts that could lead to you resolving your decreased fuel mileage. Do like upstate mentioned, and make a list and go through it. 8 pages of suggestions, you should be able to figure it out by now.

 

im not a mechanic, everything ur syaing i have to get other people to do for me so it takes time, so far ive done almost evertyhing except for checking my torque converter and changing the fuel filter, but it will be done.. this weekend im cleaning throttle body and checking for hidden codes so ill keep eveyrone posted.

 

if u're doing that rpm at 60 i feel you are a little high.... but yes the motor difference maybe there... you can easily goto a dealer drive another max of same yr and confirm those numbers.. for the OD switch please read your owners manual.

try the test i mentioned tonight... from a motor perspective... i know you have a 3.5 and i have a 3.0 but we both have a 4 spd automatic with a torque converter... this means the trans would be fairly similar in the way they work and perform...

anyways... drive out tonight after about 11pm and do that little trip.. it'll probably take up over an hour if you are going to do the 60 mile trip... but it will tell u exactly what your mpg is in the semi controlled environment where you can keep a constant speed for extended time and you dont throttle up and brake frequently... remember not below 60 and not over 70... if you can use cruise that would be the best.... and fill up at the same gas station...

 

well im gona check the lockup torque converter test tonite and see wat happens, this weekend ima do a buncha things too, if those dont work then im changing my fuel filter, thanks ill keep u updated...

 

Thats why I told you to get a FSM... You DO NOT need other people to do this for you.

Roll up your sleaves, get under/in your car and LEARN it. Thats what I did...

Just follow the directions, it is not rocket science. Several of the people you are paying $70-90hr to work on your car have IQ's in the 80's....

 

i dont have ne tools and id rather learn a little more before i start doin it myself.. whats a FSM?

 

Factory service manual.

http://forums.maxima.org/showthread.php?t=345720

 

i beleive i had one, its in my glove box, the owners manual.

 

The only way to learn is to do it yourself, not the other way round.

 

The FSM is not the owner's manual.

 

does the factory service manual usually come with the car? cuz i have this black leather book with the owners manual and some other **** that i forgot

 

No, it's huge, it would barely fit in the glove box. you don't have it, your probably thinking of the warranty supplement & service books, you can download it at phatg20.net

 

o lol, and whats on that that is useful to me?

 

Everything. Please click my link and download mmmk?

 

k, lemme try, and thanks for signing off on me while i was trying to tell u wat happened can u please sign back on

 

umm wat program do i need to open it cuz its a .RAR

 

dear god kid
the FSM is what the dealership uses when working on your car so no it isnt given to every person that owns the car. the reason...most people (like you) have no business working on their car.

 

are you unable to use google? it is blocked from your computer?
http://www.rarlab.com/rar_file.htm

 

1. + ".rar files"
2. ???
3. Profit

 

For reals.....

 

no i am but its ALOT easier for someone to just say ok download this its the best program.

 

we have all realized that you think its easier to hold your hand and spoonfeed you information.
we are getting sick of it.

 

10char

 

wow, VERY helpful. but kinda confusing REP points to whoever gave me the link to this FSM, its pretty useful

 

true dat

 

yo "the law" stop ****in cosigning on everything soonerfan says ur mad annoying

 

ohhh teh ironing...

 

you really want to make an accusation like that?
