Check the engines timing to start with. Then check the engine for proper cylinder compression. Check the ignition coil and plug wires for breaks or leaking voltage.
why does my vr commodore idle rough when at complete stop
It can cause a rough idle and random misfires because the engine will be off balance. If the flywheels happens to stop with the missing teeth (tooth) in the starting position, the the engine will not even crank.

A rough-running VE Commodore can be caused by several issues, including a faulty ignition system, such as worn spark plugs or ignition coils, which can lead to misfires. Other potential reasons include vacuum leaks, fuel delivery problems from a clogged fuel filter or failing fuel pump, or issues with the engine sensors, like the mass airflow sensor or oxygen sensors. It's advisable to perform diagnostic checks to identify the exact cause and address it accordingly. Regular maintenance can help prevent these issues from arising.

Spark plugs are used to ignite the air / fuel mixture in the engine The ( 8 ) spark plugs ( in your navigator ) are needed for the engine to run properly For example : if the engine cranks but does not start the engine is either not getting fuel , SPARK , or air Another example is if an engine cylinder is " missing " so the engine is running rough the cause may be the SPARKPLUG , coil , not the correct air / fuel ratio etc.
because that's kind of a big engine
