So my g35 sedan 05 has been making this rattle noise... Seems that's is coming from the front bottom left hand side and it's not consistent and it only happens when you accelerate and not all the time.. So I've taking it to the Infiniti dealer and after doing a diagnostic they've told me it was running lean due to the stillen z tube intake so I took the aftermarket and put back the stock intake and the noise is still there. Took it back to the dealer after runing another diagnostic but this time with the stock intake and paying again seem that the aftermarket intake wasn't the problem but they said to me it can be the mass airflow sensor but it would cost me about $400 to $500 I mean it's crazy that it would be the mafs so the dealer tech cut a deal with me if the mafs wasn't the issue I wouldn't pay sure enough it wasn't the problem they'd ask more time to work on the car but it would cost me this time so I'm still figuring out what can be the damn noise I'm tired of the dealer going back and forth.... Anyone know what can be the problem???

 

WORDS make SENTENCES. Sentences are seperated by comma by punctuation. Use it or else you will not get people reading your posts. I had to try and read it 3 times to get through it.


We can't diagnose what your issue is without hearing it. You need to isolate the location better as well.
