Most common cause. Bad plug wires,distributor cap and rotor, Bad plugs.

a bad coil or plug to be safe change both
What causes misfire 302, 304 and 306
the gun powder ispacked to tightly and the preassure builds up and can cause it to misfire
If the distributor cap, rotor, ignition wires and spark plugs check okay then I would suspect a faulty fuel injector.
what are the possible causes of misfire on number one cylinder in a dodge 2003 ram 4.7 liter engine
Spark plugs
I'm not a mechanic / technician but I BELIEVE if the fuel injector is restricted so that the proper air - fuel mixture is not getting to an engine cylinder , that an engine cylinder misfire can occur ( that is only one of the causes of an engine cylinder misfire )
With multiple misfires originating from the same coil pack, my guess would be to replace the driver's side coil pack.
A misfire on cylinder 3 in a 1996 Blazer can be caused by a faulty spark plug, fuel injector, or ignition coil specific to that cylinder. It is recommended to perform a compression test to rule out any internal engine issues and also check for vacuum leaks. Additionally, scan the vehicle's computer for any trouble codes that could pinpoint the exact cause of the misfire.
That would be that there isn't enough gas getting to them
Cylinder misfire. Possibly failed or failing engine mounts.
a bad wire or a bad coil to cylinder 5.
