Misfires can have several causes: 1) poor fuel mixture - carburetter or injector problem. 2) poor spark - ignition module, timing pickup, contact breaker worn, condenser breakdown. 3) valve face burned or leaking; ring broken or worn, piston scored and leaking. Items 2) and 3) are tested with a spark tester and ignition timing tester for 2and a compression tester for 3)

What else could be wrong if 2 cylinders are misfiring after getting water into the motor through the intake after the spark plugs and ignition coils have been replaced and it is still misfiring?
I really hate to be the one to tell you the bad news but it is possible that you have bent some valves. Take the spark plugs out of the missing cylinders and run a compression check on those two.
Does bad spark plugs give you rough idle?
Bad spark plugs can indeed cause an engine to idle rough. If any of the spark plugs are misfiring or are not producing enough of a spark to ignite the fuel, then not only will the engine idle roughly, it will alwso waste gas. If may seem as though it is running fine when you are driving however, you still may be wasting gas and your pickup may not be as fast as it should.

A miss on one cylinder is caused by defective spark plug, plug wire, burnt valve, or blown head gasket. Replace all plugs and plug wires. If the miss is still there run a compression test.

How do you check if you have spark at the spark plug wires?
you would take out the spark plugs still attached to the spark wires. place the metal of the plugs onto a grounded metal spot. make sure they are not touching in order to prevent damaging them or blowing fuses.
