Hey guys,
As of yesterday my cars (R33 s2 gts-t) been making this really odd noise, it sounds like sticking a pen in a fan, it only happens under acceleration and mainly in 2nd gear either at 40kph or 60kph, like i said its a fairly loud buzzing pen/pencil in a fan noise...though it doesnt happen all the time, it was happening all this morning then this afternoon it didnt happen once, and its randomly happening tonight...
Any idea's? Also after i got my new exhaust (catback) put on my cars been smelling fairly bad, a mate told me new mufflers do smell bad for a while, is this true?
Cheers
