I have a rattle coming from what sounds to be the intake manifold, which I could be wrong. That's just where this annoying and scarry bug in my ear is pinpointed. First question is, has anyone experienced this?

I was told by my dad that something is loose or has broken off inside the engine (I kinda figured that......dad).

Second question is, if I take this into the stealership, will my Injen hurt me in terms of voiding any kind of basic warranty? I see no reason why my intake would have caused this, but again I could be wrong.

My SES light came on today, and the rattle has increase durations a little. It's intermediate when it occurs....sometimes at idle, sometimes when I'm barely engaging the accelerator, and sometimes whenever the he77 it wants to!

Please help me before I take it in like it is and shoot myself in the foot.

Thanks,
P

 

Stop driving it....take the intake off (put the stock one back on).

Take it to the dealer....

There was a thread before about an Xtera, I think, that had that problem. Turned out to be screws that rusted off the flaps/butterflies (i guess) and were in the manifold......TAKE IT TO THE DEALER...just take off your "performance parts (anything they can blame this on)"

 

Thanks, for the info. I thought I remembered something like that being mentioned before, but I wasn't % positive. Thanks again.

 

Pull the plastic "accordian" piece off the intake/throttle-body and look at the throttle-body flap and check if any of the screws are missing.

This has happened to a few Maximas and at least one Pathfinder with the VQ35DE, I know about.

 

u can also take it to autozone and borrow a code reader if u want to pull the code.
