Question : PROTON Sagas ( not the
current model ) are notorious for vibrations during engine idling.
I have changed the engine mounting bushes but the vibrations are still bad.
My mechanic can't tune the engine much more.
According to him, "Sagas are like this !"
Answer : One solution for engine vibrations during idling is to
increase the idle speed.
Part of the problem could also be the loading of the air conditioning
compressor on the system.
