Question about 2003 Nissan Altima

2 Answers

We have a raw fuel smell comming inside our 2004 altima.

This car has been to 2 nissan dealers. Nothing found. It is not a constant smell. Will smell at startup,driving down the road, or turning some corners. It is raw fuel not exhaust. I have worked on cars and equipment for 35 years, and know there is something wrong, even though the dealers say they cannot find anything ?? It has 56M miles and has only done this the last 9 mo. My best guess is that it is comming in from the fresh air vent. Need answers Thanks.

I had the same problem the dealers were useless for 1 year. Its the o ring on your fuel pump located under the back seat. It was a simple fix last year never came back

If it was my i would get a flashlight and take a look at injectors to make sure one of the -o- rings are not leaking and checkout the intake as well.

Driving down the highway, my 2002 nissan maxima went from driving great to loosing most acceleration power and only able to go about 10-20mph max, even with gas pedal floored. Proir i was on empty and...

Sounds like you off easy with the pump. Could just be a clog or some water. Some things to remember before you go back:
1) Was it producing large amounts of steam or smoke from exhaust? A strong antifreeze smell means head gasket. This will rob you of all power. Since you will get back when it is cold, before you turn it on, smell the exhaust pipe for antifreeze. If there are any of those symptoms, get it towed where you can do some major work.
2) If no smoke or steam from exhaust, and if you are certain it is not the drive train, know where the fuel filter is and what it would take to do it along side the road (Many need special tools to remove). If more than a few seconds work and your along side the road, have it moved somewhere safe (remember, a car broken down along side the road is more likely to collect other cars than other where else). Since you just filled up, buy a siphon and some gas cans, take a bottle of "HEET" and "Sea Foam" to put in the tank. They both control H2O if you picked any up at the last fill up and start at replacing the fuel filter.

A vehicle like that won't give a poor gas milage for nothing. The dealer just don't want o deal with you. I own a 2009 Nissan Versa, which is one of the best gas milage car you can get, but right now is spending way too much gas. In my case the problem is the spark plug and the air filter, and it should be good to go. Have it diagnostic. Good luck.

I have replaced my Catalytic converter with a direct fit replacement, also replaced my engine speed sensor and crank shaft sensor and i still have my service engine soon light on. The latest fault says...

If a converter failed in less than 12 or more years--you have a problem, that caused it to fail, correct that first,then the new converter.

If you replaced Sensors yourself, based solely on codes,and did no testing,they may have been okey, and not the problem

You know, you need to get the codes, any time a check light is on,which you have. That only points to an area of malfunction within a system,not the problem or what to replace.

I hope a dealer hasn't taken you down this road,I'm guessing they have.
When you leave a vehicle at a dealer, and only have contact with a service adviser out front,no road test,no tech to talk to,how would the person assigned your car, know why it was there? You see the results. There are thousands of people on this site alone,two thirds are here, because a dealer has fixed nothing,absolutely nothing.

Without the one can diagnose all your issues.
Find a shop close to home, that is up to speed on todays vehicles

No road test with you in car--leave
No Data subscription such as All Data or Motor,Indentfix in shop ---leave. Without that they know nothing about your vehicle.
If they say give me your keys,I will check it out---leave
You need at least 15 min or more discussion about your cars history and a completed R.O. repair order,stating what your authorizing

The Rav 4s have 2 issues firstly the injectors can leak and this causes a strong fuel smell on start up,even cleaning wont fix it they need to be replaced,and secondly valve stem seals go in them meaning on cold start up it will blow smoke for a few seconds,these are the 2 most common issues as i work for Toyota and see plenty of them

Pull the trans dip stick and smell it. Does it smell burnt? Your tranny might have gone out. I had an Avenger that the tranny went out at about 60,000.

Central locking won`t lock,keeps unlocking

I had this problem on my 2004 and ended up taking it to another dealer as one was just plain incompetent. Found out the wiring was not properly grounded. Nothing like driving down the road and having all the locks clicking as well as the trunk or my favorite.....driving home in a rain storm with the window down because it would not go up. Hope this helped you.

Every time it rains, and my truck sits in the rain for an extended period of time, when I go to drive somewhere, a few minutes down the road the truck starts to stutter and shake, or **** either when I'm...

I had a 93 Nissan that had a similar intermittent problem running when wet, humid or after sitting. Usually it would start fine and run well most of the time, but stutter, shake or die. It sometimes had low power and got terrible highway mileage even though it was a 4 cyl. 5 spd. When it was dry and not humid, it ran like it was new. I thought it was the ignition wires and changed them with no results. 2 Nissan dealers said everything was fine--it never acted up when they had it. I found a web site that had Nissan technical service bulletins and found one that described the problem--there's a connector in the wiring that needs replacing. It's wrapped in black tape and is a crimp connection. Dealers told me that couldn't be the problem (it was still under warranty), so I took the truck and bulletin to a non-Nissan mechanic. Within an hour he found the connection, replaced it, and the truck ran perfect after that. Sorry but I don't have the technical service bulletin anymore. I may have found it under a different year . .Good luck.
