so recently i've been getting problems with my car..

when i'm driving at a normal speed.. say 20 mph at around 2000 rpm's or less then when i push the gas (when the engine revs to 2500+ rpm's) i hear a crakling noise.. after the first time i hear that noise. i let go of the gas and push it again and it makes the same noise..i'm not sure if its from the engine or somewhere through my exhaust. the exhaust are original but i do have a Stillen CAI w/ Z Tube in my engine.. the crazy part is this only happens once in a while, but lately its been happening more often!.

-I've heard that its becuase of the heat that the car is under??
-I've also heard that its the tranny thats messed up??

I have an 06' G35 5AT.

Thanks for looking.



ok soo update on this issue.. 9-21-07

I went to day in the morning to check this issue out. Me and the Service advisor went on a drive.. luckily the noise was there nd first he tells me that is carbon built up ect.. don't even remember.. then when i was just pumping on the gas he also heard that noise and he said we have to look at that (he said it was a ringing noise).. then he talks to some mechanic and then i go on another drive now with the mechanice.. but then he states that he didn't hear anythin.. then we go back to the dealership then the service advisor talks to the service manger nd he says we can't do anythin.. so i get pissed at him and start going off on him and then he tells not to come back?!?!.. wats up w/ tat??..

..now tell me is this noise normal?.. because they told me that your going to hear a lot of weird noises becuase "its a coupe?"..


Thanks..

 

Well first off you pissed off the service manager and he told you not to come back,big mistake.I am a service manager with a retail business and if you jumped my **** like that i would tell you to hit the fuken street.You sound like an arrogant punk with your post so you got what you deserved.

 

WTF!!.. first of all i spend so much money on this car.. nd all he has to tell me is u hear a lot of noise in this car??.. if i wanted a PIECE OF **** CAR i would have gotten a ford or somethin??..

 

Fuuck dealerships..... they can all go to hell, damn crooks. I've had so many bad experiences with so many of them. They don't give a **** about customers cars.... only selling us cars. As far as your problem, it could be several things. It should be pretty easy to rule out your trans though. If it is carbon buildup I would buy some fuel system cleaner like prestone and use it before you go on a long trip. Don't let it stay in there for a long time, use it up quickly. Redline it a few times too to help blow out any carbon.

 

yeah but, true about the Carbon built up but i only have 10,952 (and counting) miles
