Re: 2007 engine does not run like 2006 engine.
FINAL SOLUTION:
Ok, our 07 SE SUV came back from dealer's shop, and they say that it sounds "normal".
To compare, they brought out a brand new 07 SUT SE for us to test, and it does sound the same idling and during a test drive. Same vibration stopped at idle, when you touch the tires. More vibration off the front right tire than the rest. Same vibration, most pronounced at 1500 rpm and light load when driving.
I did not realize that the 06 was so much quieter and smoother!! The larger diameter pipes on the 07 create quite a roar. The 07's are WAY WAY rougher than the 06s. They apparently "improved" the vehicle. DUh?
On the positive, it gets about 1L/100km better gas mileage with the larger pipes.(= about 2mpg?)
Learn something new everyday with these vehicles!
