I just got a '07 HL Limited. I expected the V6 to be as quiet as the
previous generation Camry with the V6. When I start a cold engine, it
is pretty loud and rough for the first minute. Even after warm-up,
when idling, there is a "boominess" or like a resonance that almost
sounds like a boomy exhaust but it is not. Seems more like an engine
vibration. Also, when driving, there is a slight vibration that can be
felt in the steering wheel between 1800 and 2000 RPM. It is not vehicle
speed related. I am just very surprised that the engine does not sound
as refined as the Camry. Even in park if you just feather the gas a
bit to rev it up, it sounds much more truck like. Is this due to less
insulation on the firewall, different motor mounts, different airfuel
mixtures? Anyone else notice any of these things or am I just being
too picky and forgetting that it is still basically a truck?
Thanks
