Mopar to Ya, I can tell you a very simple way to determine if you have ignition problems - without tools and in less than 5 minutes:
Have someone crank the car "cold" while you're standing by the engine. Then, as soon as the car lights off, quickly touch the backside of your fingers to the pipes, near the cylinder head one at a time, to verify whether or not you have good spark.
Any cylinder that is missing, or not firing, will feel significanly colder than the other cylinders, and yes, the firing cylinders do get hot very quickly, so you only need to quickly contact them to know if they are firing.
Any cold cylinder can (95% of the time) be traced to an ignition issue (plugs, wires, cap, etc.).
I hope this helps as I've used this method many times over the years and it's proven reliable for me. Also, if you're not comfortable touching the tubes, a temperature gun/probe (Fluke sells such attachments for their multi-meters, as do others) will tell you the same thing and save you a lot of guess work.
