I remembered another good reason to unplug the ECU. While the engine is all apart and all the sensor wires and plugs are loose, with the head gasket and head is bolted back on top of the engine, with the camshafts and timing chains reinstalled, you need to test the engine. Before doing all the work of installing all the manifolds and accesories back on the engine, you want to test the engine to be sure the compression is good, so do a compression check of each cylinder, which requires turning on the key and cranking the engine with the electric starter. If the ECU was still connected when you do this, the ECU would turn on and see that all the wiring was disconnected, and it would be needlessly filled with all kinds of diagnostic error codes, and could be damaged. So again I say, unplug the ECU to keep it safe. Don't plug it back in until everything is properly connected and you are ready to start the engine. It is always better to be safe than sorry.

Thanks for the complete answer. I found an unplugged vacuum hose on the throttle body. After reconnected it, the pinging is almost gone 80%. Will changing the Autolite double platinum sparkplugs with the NGK Laser Platinum (OEM) help? 87 Octane (no Ethanol) runs just fine but with 10%ethanol the pinging is more pronounced. The pinging noise is not getting worse under heavier load. Just a little pinging at 1500 rpm (lean condition).
 
Is there any way to clean the combustion chamber without removing the head?

Question - "Is there any way to clean the combustion chamber without removing the head?"
 
Answer - You could try a couple of things.
First you can use a fuel system cleaner or fuel injector cleaner additive that is added to your fuel tank. This may help a little. This should be done on a regular basis anyway, at least at every oil change
Second, you can run a small quantity of water through the engine for a short time, while running the engine in Park at about 2000 to 3000 rpm. You can introduce the water into the engine by removing the small hose that plugs into the top of the rubber air tube that runs from the MAF to the throttle body. Place a small funnel into the hole, have a container of water ready, start the engine, have an assistant sit behind the wheel and control the throttle, keeping the rpm at 2000 to 3000 rpm in park and parking brake on, while you slowly pour a small steady stream of water into the funnel, listening to the engine. The engine should continue to run ok, if it starts to choke, stop the water until it recovers, then start again with a smaller stream of water. This may help remove some of the loose carbon that causes the pinging.

2002 Altima - Oil Burning/Engine Failure by nomorenissan

I've posted the question to Lawyers.com. We've had the same problem and I absolutely intend to pursue this. My son bought the 2002 Altima for $5250 with the money he has been saving since he was 12!!!! I'm so angry with Nissan, I could spit. Here is what I wrote to the class action forum....
************
I have a significant problem. My son purchased a 2002 Nissan Altima with 98,000 miles from a Nissan Dealer off e-Bay in February 2009. Even though the car was sold to us "AS-IS", the dealer was sure to tell us what a great car it was and the only reason they were selling it on e-Bay was because they could not obtain financing for a 2002 vehicle with so many miles. Okay, I accept that. We test drove the car and it was in superior condition. The performance was excellent in every way and we bought the car for $5,250 cash (my son is 17 and had been saving for this car since he was 12).
 
We drove the car home and immediately changed the oil. The honeymoon was over after two weeks when my son took his car into the local mechanic to rotate tires. A routine check of the oil showed it was 2 quarts low. Naturally, we thought the quick-lube place screwed up and we simply topped it off with more oil. After two more weeks, we checked the oil again... it was another 2 quarts low. There was no visual evidence of burning (smoke) and the car passed through NJ emissions inspection without incident... So what the heck??!!??
 
Our mechanic told us that this problem could be significant, but that there was no way to tell unless the unit was put through an expensive wet-dry compression test. Anyway, we just kept putting oil in the car and assumed that would be the standard (I did it with my Rambler for years)... But the problem got worse. Smoke was beginning to billow from the exhaust. The day before the engine blew out, I took the car to a local Nissan dealer to run a full computer diagnostic evaluation... That's when I got the news that both the engine and catalytic converter needed replacement. Even though the CAT was replaced/serviced under recall from Nissan a few years ago. The cost to me would be over $7,000.00
 
Here is the problem (and a simple Google of 2002 Altima Engine Problems will turn up hundreds, if not thousands of similar stories). Nissan issued a recall for a faulty sensor within the Altima's catalytic converter. Our Altima was taken by the previous owner in for service under recall shortly after it was issued. This sensor allowed for damage to the catalytic converter, which in turn damaged the piston rings in the engines causing excessive oil burning and ultimately complete engine failure. In cases where Nissan "reprogrammed" the sensor, nothing was done to address the CAT damage and what it was doing to the engine. In other cases, they replaced the CAT, but the engines were already burining oil and headed for doom. The damaged engines, in turn, damaged the new CAT... This is the situation I find myself in now after putting only 4,000 miles on the car since February. Bad CAT, shot engine and Nissan Consumer Affairs telling me "Sorry, it's out of warranty and there is nothing we can do"... The recall should have been for both CAT and engine replacement, but who in their right mind would assume Nissan to do this for tens of thousands of cars. All they did was put a quick patch on a festering wound and waited to address individual complaints as they arose, which is infinately cheaper than doing the right thing in the first place.
 
My sons dream was crushed and Nissan says "tough luck, kid". The car sits dead in our driveway providing a daily reminder of what scum car manufacturers like Nissan can be.

It is very sad to see another very sad message about the Nissan Altima. There have been so many sad messages written in this blog, this should be complied into a book, and should be in the hands of anyone who owns an Altima, or is anticipating owning an Altima, or even anyone who owns a Nissan. Maybe the book could be titled "The Sad Saga of the Nissan Altima and the company that made it". I know for a fact that after knowing all of this, and going through all of this with a 2002 Nissan Altima 2.5S, I will NEVER own any Nissan for as long as I live, My experience with my daughters 2000 Nissan Altima has been nothing less than a horrible nightmare.
I would recommend that each and every one of you that has been screwed by Nissan to spread the word and tell everyone that you can about this blog and encourage them to read it, This needs to be headline news. Read it from the begining, about all the people who have been so dissapointed and/or devestated by the Nissan Altima, people who wanted to destroy their Altimas or push them off a cliff, or worst. I just can't say enough about how bad these cars are, and how negligent the Nissan Company is to leave so many of their customers stranded with no hope. What they have done should be a crime, and they should pay back their customers dearly for it.

In 2001, Carlos Ghosn defied Japanese business etiquette, cut thousands of Nissan jobs, shut the first of five domestic plants to help $20 billion debt. So, most of well-trained workers (Japan and Smyrna,TN.) were replaced by cheaper labor (Canton, MI, and Mexico). He is a Hero for Nissan company that has serious financial crysis like GM and Crysler but not for us.

Well folks I had to buy a new engine. Costs were $5200. Unbeknownst to me, they replaced my precat. I had my main cat hollowed out. By still having the main cat hollowed out, is my new engine safe from debris if the precat fails? Should I get the precat hollowed out? I do not want to ruin my new engine. There is a 12 month/12,000 warranty. I have a 2002 nissan altima 2.5.

Yes...and I will never buy ANOTHER Nissan, Toyota, Honda, Subaru, Mercedes, BMW etc. etc., since every manufacturer in the world has had problems with their cars at one point or another. I am already doing research on the best bicycle that I can get (hopefully I can find one that absolutely 100% population loves).
I currently own 2002 Altima, 2007 Altima (drives like a dream) and 2008 BMW 525I and I came in here to find a solution to how to fix that damn 2002 vehicle and not all the whining about how bad Nissan is since that's ABSOLUTELY FALSE. 2009 Nissan Altima is Consumer Report's, Consumer Digest's and JD Power's TOP PICK not mentioning other Nissan/Infiniti products. Sorry to hear you had a bad experience with that car. If that was a "lemon" car there is such a thing called "Lemon Law" and you can try to get the money for your car under it's umbrella.

P.S. I just got my money back from Sony after fighting with them for over 2 years over faulty Sony Plazma TV. No more Sony for me? I don't think so..I love them. Welcome to the real world.

..Hmmm..let me think..so erasing all this debt is bad?....saving the company that was worshipped by Japanese for decades was bad?......Let me tell you something...if the business practices currently employed within your company are outdated and bad, you have to change them!
...and talking about cheaper labor....if it's so true I wonder why Nissan is doing so great since Ghosn took over? All those Nissans: Versa,Rogue,Altima.....number one cars according to Consumer Reports and Consumer Digest and million other awards for Murano, Xterra,Titan, 370Z, GT-R etc. etc. And if not for all those changes tens of thousands US WORKERS employed by Nissan would be unemployed.
HERE IS ALITTLE READ FOR YOU... In 2001 Brazilian-born Carlos Ghosn became the first non-Japanese person to head a major Japanese automobile-manufacturing corporation. As the president and chief executive officer of Nissan Motor Company, he broke the traditional Japanese business models that had stifled the automaker's growth. Within two years Ghosn had led the faltering company into a period of revival, breaking a ten-year string of losses or tiny profits. By the end of the first quarter of 2003, Nissan turned a profit of more than $4 billion. Involving himself in all aspects of the company, from designing to test driving, Ghosn made himself an icon for Japanese business culture by the middle of his second year in office.
Within months of his arrival Ghosn had laid bare a plan that would not only revolutionize the way business was done at Nissan but challenge some of the basic assumptions that lay at the heart of Japanese business methods. By shutting down plants, laying off workers, and severing ties with underperforming suppliers, Ghosn demonstrated that radical measures could be effective in changing the conservative Japanese business system. He expected the process of making Nissan profitable to take three years; it took only two.
 
Ghosn also changed the look of Nissan's line of automobiles. The leading Japanese automakers, Honda and Toyota, historically were cautious about altering the appearance of their cars. In contrast, Ghosn, according to Alex Taylor in Fortune, took risks by making over almost one-third of Nissan's product line within a couple of years. "Ghosn wants Nissan to stand for passionate innovation," said Taylor, "and insists that new products satisfy an unmet customer need" (July 21, 2003). The executive's record, the Fortune contributor concluded, seemed to forecast great things for the companies he headed

That's totally right. He is amazing but unfortunately Nissan doesn't care about the buyers after the warranty is over. 100k miles is the average lifetime of Altima 02 instead of 200k. The number of Altima 02 engine failure caused by pre-cat and bad head gasket is so big. More than 200 just from 1 website. http://www.carcomplaints.com/Nissan/Altima/2002/ They should issue a recall or there will be no altima 02s on the road several years later.
