If the valves were adjusted incorrectly, yes it can cause a miss. It can also burn a valve if they are adjusted too tightly.
if sludge is keeping oil from draining away from valve guide a cylinder can suck in oil and cause plug to misfire
The valve adjustment procedure, on a 3054 Caterpillar diesel engine, begins with manually turning the engine to the number one cylinder. Tighten the valve screw with the cylinder at the top of the stroke. Doing this for each cylinder.
A burnt valve will cause the cylinder to either be week or misfire completely. Depending on how much compression is present. Sometimes after reaching crusing speed it feels as tho the cylinder is pulling it's weight, this is not true. The only way to correct this is to pull the head and do a valve job. I would reccomend doing both heads at the same time if applicable.
Local shop told me that there's no need to do valve adjustment on 2003 Accord.
