After 4 years of faithful service I sold my 01 Sequoia and have just taken delivery of an 05 Limited. All in all it is a more refined package than the 01 and I am very pleased. There does seem to be some sort of a resonance sound at 1,700 RPM in the first 3 gears under light load ( when accelerating with light throttle.) I am curious if any other 05 owners with the VVT engine have experienced this or if anyone has any theories. I have less than 100 km on it so perhaps this is something that will diminish with beak in.
