Replying to: marcogallo1986 (May 02, 2008 6:19 pm) actually, the oil consumption problem was fixed as soon as it was recognized. the whole thing is caused by a too rich fuel mixture. the recall to re program the ecm corrects the problem. I'd be willing to bet dollars to doughnuts that the majority of cars experiencing the problem were either: 1. never had the recall performed 2. the recall was not done correctly.   Thats part of the reason I no longer buy used cars. it costs more buying new, but I know exactly what I have, what's been done to it, and how its been treated and maintained.   as for nissan reliability, I've posted it many times but, I've owned 3 nissan vehicles. 2 long term. my 07 altima is only a year old. my first nissan was a 1990 sentra that I traded in with 220k miles, 12 years old, and still running. the only work that was ever done to it was 1 CV joint, 1 CV boot, brakes, muffler, and an oil pan, though that was because of something the wife ran over . Plus routine stuff like oil changes and so on. My second nissan was a 1998 200sx (coupe version of sentra). I still own it, have 156k miles on it, drive it to an from work most days (mostly because I get about 38 MPG), and have not had to do any non maintanence work on it. that 9 yr old car with 156k miles on it has had the front brakes done twice, and thats it. the rear drum brakes are original. as are all the belts, hoses, clutch and so on. 2 brake jobs and thats it. and on top of that, the car has never broke down, or failed to start in the morning. It's been 100% perfect, as was the sentra.   Thats not to say nissan is perfect. I don't know if they've improved things, but nissans have always rusted excessively IMO. Not so much as to shorten their lives, but more than other cars do. Nissan also has about the worst paint/process of any car out there. Its soft, thin, and chips easily.   but if properly maintained, they will last longer than you need them too.
#270 of 500 O2 cheater? by coop0129 May 14, 2008 (6:11 am)
I have a 2002 Nissan Altima 2.5 with all of the recall work performed. I think I may just hollow out my cats sometime in the near future just to do it. I don't want the check engine light on. What can I do to fix that and the light will not come on. I saw that someone said a $5 O2 cheater? What is that? My car has 95000 miles on it. Thanks.

Replying to: coop0129 (May 14, 2008 6:11 am) something like that. the problem with hollowing out, or removing the cat is that there are 2 O2 sensors. one before, and one after the cat. if the both get the same reading, your SES light will come on. I'm not sure if you misspoke, but you said you might hollow out your cats. Don't do both. Its just the first (precat) that can cause problems. It's too close to the engine. the second cat farther down the line will not give you any problems. And, you'll need that second cat to pass inspections. anyhow, here's the link with your options. you can allways get a new header instead of hollowing out.   link title

Replying to: coop0129 (May 14, 2008 6:11 am) Why do you want to hollow out your cats, and why BOTH cats? That is drastic action and should not be done unless it REALLY needs to be done. You can't pass an emissions test if you do that. It depends on where you live and what kind of emissions testing that they do, it varies state to state. My state does not have any emissions testing, but yours might. I think a problem here is that people wander on to this site and read a message or maybe a few, draw some short conclusions, and make a comment , without really knowing the facts and doing the research. All the answers to what you need to know ARE in this forum, they have been posted over and over again. Please do some research and look for them. You read my post about how I hollowed out my cats, and you just assumed that you should too. Wrong. I hollowed my cats out for a good reason, because they NEEDED to be hollowed out. Few people have that need. Please go back and carefully read posts # 75, #76 & #77, and you will find out why I had to hollow out both my cats & what you need to do. In fact you should go back and read all the posts before yours, as they contain a wealth of information, including the $5 O2 Cheater, how it works and how to install it.
#273 of 500 Misfire by smoothride4me May 17, 2008 (9:35 am)
I have an 02 Altima, Took it in to the mechanic and it showed that the #1 cylinder there was a misfire.. It stalled at the stop light and hesitates like a misfire on the freeway. Any idea ? Replies to this message: electricdesign (May 17, 2008 4:12 pm)

Replying to: smoothride4me (May 17, 2008 9:35 am) That miss could be from a lot of things. Need more info. Do you have the 2.5L 4 cylinder engine? How many miles on the Car? Is the Service Engine Soon light on? Does it miss when you first start up? Does it clear up sometimes and when, if it does? Does it miss the same all the time. Does it vary under different conditions, like cold, hot, fast, slow, braking, accellerating, etc. What else did the mechanic say? If he found the code for the misfire on cylinder #1, didn't he do further diagnosis? I would check ignition fire on all 4 cylinders and to a compression check on all 4 cylinders to start with. Have all the recalls been done? The camshaft sensor and the crankshaft sensor starting to go bad could cause things like that. Has the engine ever got hot? Those engines are sensitive to overheating and the head can warp easily, and when they do, it usually causes a head gasket leak. A head gasket leak will cause an engine cylinder miss. How is the engine coolant, is the coolant reservoir staying full, or do you have to add radiator coolant once in a while? Please elaborate with as much information as possible. Good Luck, E.D. in Sunny Florida
#275 of 500 No power by yankees1313 May 18, 2008 (10:37 am)
I have A 2004 Altima, it has no power. I tried the battery in my other car and I heard something frying when i hooked it up. i'm pretty sure I hooked it up right. Maybe i didn't but now even with my original battery in when I try to jump it nothing happens, I get a 0 on the dash and the both turn signal lights on. Any suggestions? I notice what looks like a computer chip or fuse box on the red possitive cable could I have burnt that out? Any help is appreciated

Replying to: pdupuy (May 02, 2008 6:20 am) I'm having the same problems so your not alone! Unfortunately I still owe too much to trade it yet, but I will go back to American vehicles when I'm able. My advice is to do the same.

#278 of 500 '05 Pre-cat Failure by ckeough May 21, 2008 (6:39 am)
I have a 05 Altima with the 2.5 engine, 31,500 miles, which I bought used about 6 weeks ago and have put 1200 mile on. Last week the SES light came on and I had Autozone pull the code. The infamous P0-420.   Yesterday I had a dealer check it out and they found the pre-cat was "coming apart internally" and replaced it under warranty. Hopefully, none or very little material made it into the engine; I'll be keeping watch for oil consumption and hope that any problem with that shows in the next 30K or 2 years while the drive train warranty is in effect.   So, either the pre-cat was just a bad part or the '02-'03 recall situation will be continuing as all 2.5 reach higher mileage.   Anyone know if or what changes were made for the 04-06's at address the failure of the pre-cat? I'm thinking none other the the ECM re-programming to maybe lean out the engine.   Chris Replies to this message: jd10013 (May 23, 2008 1:39 pm)
