i'm just new with honda car. I just have bought a honda accord 2.2 (a) 1997 last month.
My car vibrates when in idle mode. is that because of engine mounting or something else?
Can anyone here help me? I'm try to use engine oil Mobil 1 5W-50 for my car. is that best or worst to my car engine? plss.. i need help.

 

check to see if it is misfiring

check your rear engine mount and make sure it is working properly

 

5W-50???
im guessing that was a typo... but you should use either 5W30 or 5W20.
mobil 1 is a good oil, as far as oils go.
As far as synthetic oils go (the best in most areas) some of the best are royal purple, amsoil, and Valvoline SynPower.

 

like it was mentioned, You need to verify if it is an engine miss or bad mounts. And also use 5w-20 or 5w-30 oil..

Pull plug wire one at a time and see if the idle speed drops or stays the same.. if idle speed drops that cylinder is firing.. if idle speed stays the same that cylinder is not firing ( engine miss)

 

yeah, check motor mounts.

is the idle speed steady?

possibly balance shaft alignment wrong?
