deceleration while giving the car a little rev in nuetral. Mine does it sometimes and othertimes not at all. It's just a faint little chirp as the rpms are falling around 1500 rpm. Not to worried just curious.

Thanks,

Eric

Not sure about the exact issue you are talking about.... but if you mean sort of a whistling chirp, then it's probably twitching of the BOV when you are near the 2000rpm range.

Common... It's been attributed to the exhaust hangers. I switched to Kartboy exhaust hangers and my "chirp" went away. :D
