it happened about 3 or 4 times recently.
When I turn my car on, i feel some very unpleasant shakeness through my gearbox and whole car. like a tractor
Could it be coilpack or one of spark plug out?
If I turn the car off and turn it back on after few seconds it is ok.
Do coilpack or spark plug go off instantly or die slowly like on off on off...
any idea?

:nod: Could be running 3 cylinders. Check the sparks first, then the coilpacks. Dying coilpacks do so intermittently to start with.

If you've not change them recently, do so.

To trace a coilpack problem, you could do with borrowing a spare. Check that all the connectors are secure first :nod: Leave the spark cover off. Next time the car does its rough running, leave it running and tweak each connector to see if the problem goes.
