drove my car last night and i noticed a very subtle rattling sound especially when shifting gears. i had to turn off the radio to hear it better after that i was sure the sound was coming out of my engine.. im thinking maybe because i used lower octane fuel this time but ive been switching from 91 to 87 sometimes(when i decide to be el cheapo) but never had that kind of thing happen before.. and oh yeah... just took off my CAI, cleaned my MAF and TB and turn CAI into SRI (cause im worried bout hydrolocking cause rainy days are comin up...) but i seriously doubt that caused it... anyways, anybody had or have the same problem? know any fix?


thanks,
Gil

 

I had the same problem, but it was more around 4000 rpms. I took it down to the dealer and let them listen to it. Turns out a heat shield was loose and about to fall off. They tightened it up and I was on my way. Take it to the dealer... that's what warranties are for.

 

will do.. thanks for the info..
