I was informed I have a dead miss on my 2nd cylinder, which is also only pushing out 25 psi. Was confirmed that it wasn't anything "on top" like a spring or something that could be easily fixed. My question is, if I replace the spark plug prior to fixing the internal issue will the engine run any better?

With only 25 psi of compression changing plug would be a exercise in futility
