Vibration @ The First Start And Cold Engine

[ashan82]

Dear AL Experts

my mazda familia BJ5p 2003/auto, giving vibrating sound, drrrrrrrrrrrrrr, which comes under carriage / silencer bar area, only in cold engine (first start every day) and most of the time after shifts to gears (Some times when "P" position as well) This will go off after 10-15 seconds

there is no feel of vibrating the steering wheel just drrrrrrrrr sound from under carriage

car was checked by one good garage person as well as a silencer repairing bass but both could not find the issue

looking for you experts advice

Maybe a hardened silencer rubber bush/mount that softens when the silencer heats up?

The sound is only when the engine is at idle ? could be that your rpm is low which is causing the vibration.

Idling is normal. most of the time when shifts to "D" OR "R"

A proper RPM setup if vital. Just recheck with AC on and off on cool engine .Guess you need to attend a professional tune up and an auto choke diagnose including auto choke vacuum mechanism check. Dont forget to check all engine/ tranny mounts as well.Not a big issue.
