Well Thanks for the complements, but my car is a Milano Red EX 5-speed Coupe. No stick on the V6 models.

If the noise happened after the belt change it is either the balancing shaft belts or maybe the tensioner.

If it is a buzz look to replace the timing belt tensioner my buddy had his go bad on his lude. The dealer fixed the entire exhaust before finding the buzz was in the belt tensioner. His sounded like a shield rattle but he didn't have vibration.

It sounds like you need to make an appointment to see your local qualified honda dealer.
