When i start my car, doesnt matter if its hot or cold.
the car can take up to 1 second to finally start.
One time it didnt start at all at the first crank, but did on the second.

any ideas?

also.. When i turn the car off. the engine stops abruptly.
its not gentle, it shakes alittle bit and then stops.

 

how are your spark plugs?
use only 91 octane gas?

 

looks like the hard start was gas related. got that fixed.

The abrupt shaking of the engine is still there when i turn my car off.

 

ck motor mounts
front and pass side are common failures
