Hi, Yes it certainly could be especially if water gets in. You should also check the distributor cap. The misfire sounds like an arcing problem so it would have to be one of those two things since you changed the rest. Good Luck!

A misfire doesn't always have to be ignition... it's just the most common cause. Faulty or plugged injector, low compression. You need to check fuel pressure and test the fuel injector flow. Then check compression. If you don't have tools for these tests, take it to someone who does. Testing is much cheaper than throwing parts at the problem.
