last night... driving 70 on a highway ..windows down ...a/c off ... then "service engine" lites up ....wtf?? i was told that since i had gotten gas the same day if i dont securely tighten the gas cap that it could have possibly been that. any advice?

 

Yep. That could cause it. I have the same thing now almost continously because I need to replace my gas cap. It's fouled up for some reason.

 

damn has anyone else had the same problem... shessh i have a Chrome NISMO cap in it too... ;o/

 

Happened to my friend's Jeep. Make sure you tighten the cap until it clicks. And I hope you were joking about the cap---->

 

If you don't tighten it all the way, you can get a "major evap air leak" code.

 

in other words .. replace the gas cap?? NISMO cap setup has won me a couple shows by the way. other max's didnt even think about gettin em till they saw em on mine.

 

Don't replace it, tighten it.

What kind of shows are you entering? I wouldn't think that a gas cap would be the mod that puts you "over the top" unless, of course, you're competing against a bunch of 16 year olds in civics.

 

local shows ... you compete vs. your car make... every bit counts is what im sayin. u get two of the same max but one with different or "unique" caps... who do you think would get more points ?? i dont take the shows seriously.... and yea theyre are some spoiled *** kids...16-17 year olds who have their rides all souped up. in any case thanks for help.

 

ford's seem to have a nice problem with gas filler necks cracking and causing evap codes/leaks just my .02

 

i had the same prob with mine. i took the cap, and wiped it with dry rag, then slighty wet the rubber seal with tire wet. screw on until it clix once or twice. i had to make 4 or 5 separte trips, with turning my car on and off untill the cel went away. i now tighten the cap till it clix, and never had the problem since.

 

In Jersey, we can't pump our own gas and it's always a pain in the butt when the attendant screws the cap on and tightens to only one click. I have to get out and pop the gas cover, and tighten for a few more clicks.

 

thanks again... yup might have been a dumb question. so be it.

 

Got any pics? Is is the whole gas door & assembly or just the cap that says Nismo on it? I'm just curious to see how it looks.

 

yup happened to me twice. once when my wife drove my car and didn't put the gas cap on tight. the second time was 3 days after i picked up my 03 the cel came on. i got out tighten the cap and about 1/2 mile later the light went off.........

 

My 2003 will reset itself pretty quickly after a loose gas cap. My mom's 2001 takes about a tank befor it resets.

Simple problem, but a PITA.

Yeah I Got This The Other Day Po455 Code Evap System(gross Leak)

 

my 02 has this problem alot, even after i tighten teh gas cap, sometimes it shakes loose, it takes about a half a day for it to re-set itself. common problem i would say.

 

you actually won shows because you had a NISMO gas cap?? that is weak!!! does the exact same thing as the stock one. why dont you get some real NISMO parts?? o yeah thats right..they dont make them!!!

 

Now look, he probably won't post the pics so I can laugh at them. Thanks Sooner... TCU, huh? That's gotta blow.

 

y did nismo skip over the 5.5gens?

 

b/c they skipped over the 5th gens.

 

b/c they skipped over Maxima.

 

NISMO is mean to the older maxes they should make some parts for all of us. Grocery getters or not we all deserve sport tuned performance!

 

what are you talking about? our season opener is this coming sat vs tulsa

 

haha ... how bout "google.com" type: Nismo Gas Cap ...wow!!!!! if ure lucky they might show the image!!! woo hooo!!! what a concept. mine is in chrome. yea nismo might have crappy parts but theres nothing wrong with representing "Nissan Motorsports" is there .... Maxima is from nissan ..aint it!? har har har.

 

how pretty

 

WoW mAd StReEt CrEd Y0!!111 I bEt yOu GeT sOmE mAjOr Hp!!!!111

 

Why aren't you allowed ?

 

In some states the legislature has passed laws saying you can't pump your gas. Its weird if you ask me, I think it is to try and cut back on stealing gas or something.

 

pretty sure that Jersey is the only place like that

 

Oregon does it to....I got yelled at for it by the gas station attendant

 

Yup, Oregon and New Jersey are the only two states that don't allow you to pump your own gas. It's pretty convenient when it's really hot or really cold but if I had the choice, I'd rather pump the gas myself.

 

The People's Republic of Oregon is like that also. It's a $500 fine if a gas station allows a customer to pump gas themselves.

 

Yeah, and not have to wait 5 minutes for them to start pumping and another 5-10 minutes for them to return to hang up the hose. Getting gas in OR can be a 15-20min ordeal.

What also makes it annoying is when you forget to tell them to put prem. in it and the professional gas pumper doesn't see the label on the gas door saying "premium fuel recommended."

 

BMWs will set the Check Engine light and it will not reset itself. You have to pay for the codes to be pulled and cleared if you are sure its the gas cap. However the new ones now have a check gas cap light to solve this problem

 

well this is a nissan forum isn't it?

 

Well I happen to work for a BMW service department... SO I see what goes on in there. I thought maybe something I said would be important to someobdy

 

I know where you work.... Get a bmw primer grey

BTW no one cares about bmw's

 

I DO!

<---- look. I love these cars, most are fast and they handle awesome and the brakes are magnificent. All better than your car

 

I had a problem like that, thought it was my gas cap cuz after i fixed it it went away. but a few days later it came back.. did this a few times b4 having it checked out. turns out it was a bad o2 sensor. Go to autozone, they give complimentary code checks and can look it up inside to see what ur car is cryin about. hope this helps....
