one thing you should check maybe one of your spark plugs blew out or the one or two of the wires went bad that is not too bad.
There are many reasons why your car might vibrate while it is idling. It could be running too hard for example.
It is idling. This is hard for an engine to do smoothly.
My Toyota corola 1.6gl 1989mod 16valve, lost the idling. wat can i do to fix it?
Possibly due to engine mount
clean your injectors.
Could be EGR valve sticking open or dirty at an idling condition or hesitates when accelerating.
Loose motor mounts.
Dirty fuel injectors.
Is the AC turned on?
My guess would be to look at the motor mounts to see if they are loose or broken.
7 degrees idling @ 500rpm (650 for USA)
