mechanic paint spark plug , I order to avoid unstable due to high vibrate.
One of the things that a mechanic could be told to buy when working with spark plug wires could be a spark plug gap wire gauge. Another thing could be spark plug wire pullers.
If you know that there is spark at the distributor cap then I would think it would be bad spark plug leads.
A drain plug for a spark plug? Now why would there be? What would you drain from a spark plug.... the spark? If you're referring to a plug for the spark plug socket, I'm sure you could find something that would fit that would keep out debris while you let you engine sit without plugs. (Why??)
I'm not a mechanic / technician but it might be the spark plug , spark plug wire , not the proper air / fuel mixture to that engine cylinder , and there are probably other causes
According to my car mechanic this vehicle has coil overs, not plug wires.

A platinum spark plug last longer than a copper spark plug however you're trading off engine performance for longevity of the spark plug. An iridium spark plug last longer than a copper plug and engine performance is at its best for the longest time. but its going to cost a few dollars more for these plugs. The champion or the a/c delco have been around for years and they will last for up to 20,000 miles. If you are mechanically inclined and you can change the plugs yourself the champions will be fine. Just change them when you need to, but if you have to go to a mechanic every time , then i recommend buying the expensive iridium from your local o Reilly auto store, or auto zone and then go and have them put on. It would be a little cheaper than purchasing them at the mechanic shop.
The spark plug gap for a 2003 Buick LeSabre should be set at .060 inches. The best spark plug for this vehicle would be an Iridium plug.

Some of the repairs that you can do at home if you are a professional mechanic is repairing front brakes, oil changes, spark plugs, spark plug wires and tires.
The Champion RC7YC spark plug is not the recommended spark plug for the Polaris Sportsman 600. The correct spark plug for this model is typically the NGK DCPR7E or equivalent, depending on the year. Always consult your owner's manual or a professional mechanic to ensure the right fit for optimal performance. Using the incorrect spark plug can affect engine performance and reliability.
I'm not a mechanic but it sounds like there has been a mixup involving your spark plug wires , either at the coil pack or at the spark plugs
