OK guys here is the story. The engine started PINGING under part throttle at low RPMS 1,2,3 gears that I could notice. I thought my wife a picked up a batch of gas. So we let it go all the way down to empty I mean ALL THE WAY. So I filled up yesterday at a station I have been going to for many years( Shell) and yes we always 93 or 94( Sunoco).. And It still did it. Mean it sounds really bad if I presh the gas had hold the break( Semi brake stand) It PINGS like crazy. I know the the timimg guides on our cars are a problem and my warrenty runs out on TUESDAY, Man we are cutting it close. So I will be dropping her off tomorrow at 7am to see if the guides are bad. Is this the only issue we have with the timing cause it's being pulled like no tomorrow.. Will keep you updated.. Thanx Guys..

 

Well updated this AM and it was a Idle issue, Car was runnig lean. I did the idle reset after the Nismo CAI but maybe something else was wrong. Anyway they did the idle learn alingmrnt so it is all set and yes was covered by warrenty.. Cool dealer I was worried they would charge me cause of my mods.. Clay Nissan +1

 

I dont think Nissan can void or charge extra on top of your warrenty because of your Nismo parts. As long as they are genuine Nismo parts then dealerships shouldn't give you any problems. Glad you got the problem resolved

 

Yea I think I spoke too soon, As I was driving the car home and it was still pinging now worse than before.. So car is going back tomorrow. Had them open the RO yesterday when I called them back to tell them it was still making the noise..

 

OK new update, Dealer called and said they spoke to the Nissan Teck line and they have not fix for my car, They want me to remove all the Nismo stull and go back to stock and see if the noise goes away. 1) I do not have the stuff and two who wants to pay someone 85$ to out the factory exhaust back on just to see IF it works. Also they said there was a claim at Nissain and when I told them I did not have the stock stuff they gave me the clai number to call Nissan and talk to them about me not having the stock equipment.. SO I call Nissan and the claim number they gave me is a no go( No claim) Nissan also checked by my VIN Nothihng. So I opened one.. Get this the dealer also told me that the tech said it is ok for me to drive the car with it pinging.... WTF Ok the pinging is predetination and thats good??? Yea if a wanna crack a piston.. Looks like they do not wanna fix the car after all.. Any advise guys and gals???

 

what mods do you have? I only see Nismo intake and Nismo catbak from your sig.
Since they are Nismo products, I think the dealership shouldn't make you go back to stock. I'm not exactly sure if you guys have sensors on your catback system but I dont think the catback system has to do wit your engine pinging. Only thing that you can't argue with them is your Altima Nismo. Have you talked to the manager yet?

 

No, called him a few minutes ago and waiting for him to call back. I only have the mods in my sig, nothing else.. I think it's crazy to have me remove Nissan parts and replace them with nissan parts.. ??

 

OK Manager called me back and told me the the readings they have on the AF's are 130 and stock should be 95. He was very cool and said we are kinda in a gray area with the Nismo stuff and we will see what Nissan says tomorrow when they call me back.. How could the AF's be that high at 130.. ?????

 

I thought genuine Nismo parts are covered under warranty ( except cams)

 

We both think there are but there are telling my the the car is sucking to much air, Should only be at 95 and it's at 130 so they told me to remove my Nismo and replace it with the stock air box and se if it changes. 1) I do not have it any more( Sold it) and two thats no the problem. Nissan would not make parts that causes the cars to fail. I asked itt he MAF sesor was checked and he said it looked to be ok and if it was bad there would be a code? Then wjy id there not a code for the air flow to high?? The o2 sensors should pick up that the mixture is lean, Right..

 

1. should have gone w/ fujita LOL...

2. Should never have sold your stock parts... come on man LOL..




nismo is nissan like you have all said... i dont see why you would need you to change back..

Maybe your intake is not installed correctly.. i know from past threads that you said you checked it ... but have them check it... Just a guess

 

I know right should have kept all the stock stuff and got the Fujita, LOL. But the intake would have to be sucking air in after the mas air flow sensor. I can check it again 4th time when I go home but if it's not leaking there then I have no clue. What about a bad MAF or clogged injector. I'm trying to think of things that would lean out the car..

 

Maybe its a lemon? JK JK

 

OK Nissan just called and they going to talk to the dealers service manager tomorrow as he is off today. They still are sitting on my Nismo stuff causing the issue. Why the hell would Nissan make parts that casue problems. Maybe we will find out the Nismo stuff voids your cars warretny?? GOD I hope not.

 

It's not the Nismo CAI.....I have one on for over a year, no problems. A CAI is basically a CAI, there really isn't that much difference. The don't know what they are doing, so they are having you go back to stock just to eliminate the intake from the equation. I bet it's the MAF sensor gone bad.

How often have you cleaned your Nismo filter, you MAF could have gotten dirty if you don't clean it enough or ruined, because of too much oil on the filter when you cleaned it. If the MAF is bad, your stock setup won't be right either. Maybe Winterfaust will chime in. I'm going to PM him.

 

It doesnt matter if is it's CAI, WAI, HAI, stock intake, or no intake, as long as it's a genuine Nismo product made for your Maxima, they can't void jack on your warrenty. And if they want you to switch back to stock JUST TO SEE if same problem accures then they can order one themselves and put it on your Max. You did nothing wrong by using Nismo products that NISSAN sells. I would be pissed if I were you after getting all this BS.

 

From the Nismo catalog

"The S-Tune NISMO parts carry a basic warranty of 12 months or 12,000 miles, whichever comes first. However, the parts are warrantied by the factory only if they are purchased and installed at the point of purchase of the vehicle, in that case the regular 3 month 36,000 Nissan warranty applies."

 

Ok, Had this issue back in JUNE with another 6th gen. IF the alpha is at 130 or so on one or both banks AND there is either a cylinder misfire or a code saying the MAF is bad have them check the EGR solenoid actuation. Have them check if it is opening and closing properly. I had one that was not working correctly and did exactly the same things you are talking about. We replaced coils, injectors, MAF, Plugs etc etc etc... CHECK THE EGR!!!! heres the topper... ours had NO egr code... none..

 

I would get some CRC MAF cleaner from Autozone. Are you really sure you have no air leaks between MAF and throttle body? The air hose to the intake is on tight! No other disconnected hose?

Have you tried to do the "Idle Air Volume Learning" or "Accelerator Pedal Released Position Learning/Throttle Valve Closed Position Learning" if battery was unplugged? Is battery voltage above 12 volts with key off?

Maybe an EGR valve stuck open. Lots of unmetered air.

 

Theres some good advice for you.

 

Intake filter is spotless. An there was not to much oil on the filter checked it twice before I installed it. I think also the MAF is bad but they keep telling me if it was the check enigine light would be on.. But I still think its bad. But the sucky thing is its not covered under warrenty, How the hell is the MAF which is catorgorized as a Powertrain control modual, Not covered under the powertrain warretny. Anyway it cost like $500 for the whole thing or like $260 for the element only. Maybe some one can chime in on if I need the whole peice of plastic or just the element only..

 

I am getting pissed I have to go back tomorrow and they are checing the canister on the front end of the car. God knows what that does.. Is it the canister??? I agree if they want me to go back to stock then they should oder the parts and install them..

 

OK for winterfaust also. I will pick up some cleaner on Friday. I have checked the install god like 6-7 times sprayed card clearner on it to see if it was leaking and pulling in air. An it's as tight as a drum. The only code I have had was idle is too high, an yes the dealer did the idle relearn program on Monday. I can ask them tomorrow to check the EGR also while they are checking this canister in the front end..

 

I found the MAF online for $410. Possible to go a little lower maybe. If that turns out to be the problem.

 

Hey Thanx Apollos2, I will keep that in mind, I just hope thats not it.

 

OK nothing found at the dealer this morning, No surprise. I have not had a chance to check it myself. I will check it today and also have the MAF cleaned. Picked up that from auto zone. LOL it says gain 2-10 whp just by cleaning the MAF..

 

LOL nothing like an extra 10whp from some spray cleaner.

 

what so funny? i sprayed twice and got 16whp. not sure if my maf can handle 3rd spray and im fine wit h0w it prefrom so no 3rd sprey

 

i hope you are kidding... and did u dyno each time after spray? LOL

 

I hope so.. But they will pu anything a bottle just to get you to buy it.. LOL.

 

a friend of mine has a nismo exhaust on his 05 altima, and from what he was told the Nismo parts won't void your warranty IF AND ONLY IF they were installed by a certified nissan tech at a dealership, but if it was a self install, no warranties

 

OK guys still doing it , the dealer suxs FTL, I'm getting a 07 MAF from redls1 and putting it in to see if the nosie goes away, Also Nissan is calling me on Tuesday and going to asked them if I can go to another dealer( Better and see if they can find the issue) As far as the Nismo stuff if was installed by an ASE certified tech just not Nissan..

 

Hey, thats a good idea, swap out the MAF from another 6thgen and see if the problem disappears. Also did you have the dealer check out all that stuff what Winter told you about?

 

I tried they did not want to even look at the EGR valve. they said it was a waste
of time. When Nissan calls me on Tuesday I will ask if I can take it some where else..

 

OK Now Nissan has nothing for me. I can take it to another dealer
but I would have to pay $100 for the Diaq charge and then I would
have to call Nissan with what they find. Are you serious I have to pay
for a issue that hppened under warrenty and had the back to the same
dealer three times for nothing.Lets just hope the MAF a got off here fixes
the problem and I do not have to deal with this anymore..

 

Dang that's jacked! Keeps us posted on the other MAF.

 

OK guys hope MAF is here today. Driving home last night, driving up the hill on my street and wife says" What the hell is that nosie mad loud" ofcourse thats the pinging
it does at low RPM. Any how if the MAF dosnt fix it the car is going to Infinity for the G35 sedan. I love the Max but the pining will shorting the engine life and do not want to spend $$$$ chasing th issue..

 

damn man, hope it all works out for you, dealerships SUCK

 

Thanx man And yes they do. Waste of my and wifes time to bring it to the three times.. The thing that kills me is that Nissan did not help at all.. They should pay for the Diaq time( 1 hr and the other dealer). But NO I pay then have to call and probally
fight with them to fix the car.. Sux man, Here comes a G35..

 

Serious? I thought you were trying a spare MAF first?
