On my insight the motor has started making a noise like an old starter cranking continously at rpms of 1500 and above, I can't figure out why, also am getting some chugging. Spark plugs were recently replaced but I have no idea why that would do this.
I am temped to do an oil change at 1000 miles (synthetic too) just in case something strange is going on, belts and whatnot seem to be fine
