[NismoMaximaNY]

Hey whats up guys. Im in need of a good mechanic that can check up under neath my 2003 Nissan Maxima GLE for a rattling noise i hear when im at about 1500 - 2000 RPM. I use sunoco ultra gas and i already used chevron techron fuel cleaner and i still so happen to hear the noise once my car is warmed up. I checked for any loose heat shields and nothing is loose. Everything is intact ! I really need you guys help on this one ! i'll greatly appreciate it. Thanks !!
