hey guys I've been having an issue mainly with accelerating. Today I turned on my car (it's been sitting since I upgraded vehicles.) I turned it on and reved it up a bit and I noticed there was this rattle everytime I rev it up. Any ideas?
I got the 2k2 maxima gxe model. heres what it sounds like.

Bump

Anyone got any ideas?

 

perhaps check the front heat shield on the exhaust, they do have a habit of becoming loose and creating a slight rattle noise.

 

when was the last time you checked the oil level?

 

I'll check it when I have time. I'm sure it should be ok
last oil change car was fine and I just recently changed the oil 3 weeks ago and car has been sitting for 2 weeks so the oil thats in it right now only has like a week of usage

 

i am having the same problem. it is such a small slight rattle. right at the end of the rev

 

I was doing some research I know about the famous rattle lots of people get when their engine is stressed roughly 2k rpm perhaps it's the same thing thats making the sound?
From what I hear it could be either the heat shield or the precats more than likely the precats.

 

If you ever find out where the noise is coming from, please let me know, bc I have the exact same noise on my max

 

One detail, on my car, it only does that sound when the engine is warmed up. If it is cold, no noise for some reason...

 

Well, I finally decided to get under the car while my friend was reving it up, and it's definately coming from inside the rear pre-cat. Nissan quoted me $785 just for parts...

I can get one on eBay for just over $200. Anyone has experience with ebay precat for their max?

 

Since the inside of my precat is all blown up, I figured it probably partially threw all kind of **** up the third catalytic converter located downstream of the Y-pipe and most likely partially clogged it up so I will probably go ahead and replace this one too. Since I'm cheap, I was thinking of pulling it off, and removing the honeycomb thing inside the cat with a hammer and screwdriver, and put it back on the exhaust as is... Is it a good/bad idea?

It will probably throw me some codes but I don't care, but my question is: will it decrease the performance of the car since it will fool the 02 sensors?

 

Alright, I had the exact same problem with my Max coming from the rear precat. I bought a precat on eBay for about $280 and paid a local exhaust shop $75. 2 hours later, the noise is gone

So now you know what to do!

 

thanks. I'll check up on it hopefully my mechanic wont charge me an arm and a leg for the work
