V6 engine quake - idea?

Unread post by arnoldf »

Hi All!

My 3.0V6 engine doing small quake at around idle speed. (Idle speed is looks like stable...)
Sparks replaced, no error readed via OBD.

Around camshaft belt every parts replaced, and checked.

Anybody has idea? Or anybody knows a typical problem which cause quake?

My last idea only the ingnition coils. But hard to check which one is defected. :(

Thanks in advance, and sorry for the english post.

Checked, okay!

(Removed and engine started, no change. What mean the source of the problem is not alternator, servo, klima etc etc,)
