Hi from MWOS
My 1999 3.3 v6 Dodge Caravan has a vibration sound (buzz) at about 2200 rpm when ingine is under load.
vibration is not felt, only heard. again heard about 3200 rpm.
all other speeds quiet.
It is related to rpm. changing the gear the transmission is in does not seem to have any effect. car runs great except for this noise.
anyone have a suggestion?
