Sure.
Too low a voltage can cause the spark to be weak which is first seen as missing
higher revs and gradually goes to missing at lower revs as the battery gets
lower and the spark gets weaker.
I just had the other extream happen to me last week. Shot voltavge regulator
caused 16 volts to be put across the battery. Battery erups fluid whick pours
down onto the electical connection of the fuel pump. Connection oxidizes
quickly causing high resistance electrical connection slowing down fuel pump to
where it can not keep up with engine at higher reves, then over time with lower
revs. Result missing because of fuel starvation forst at higher revs then at
lower revs as connection worsens. had to replace regulator and clean fuel pump
connection.
Of course now, many things can cause missing. A very common and often
overlooked cause is a clogged fuel filter.
