Not True... Just do not know how.... Most people I ask questions about their car know NOTHING about their car.
lol i agree. i live in an area where tuners rule the streets. i see some guys riding around in there hondas, next day they have a PRESTINE mustang or camaro so i ask them about it. the faces i get are hilarious
the fact that the vibration is blury tells me it every cylinder causing a consistent vacuum fluctuation. im confident that the cam you have is responsible for the the fluctuation
