Why does my 2-stroke misfire?
An oily build up on a spark plug will cause the spark plug to misfire. Oily build ups are very common on 2-stroke engines from improper mixture of the oil and fuel. To check this, remove the spark plug, inspect it, clean it off, gap, and re-install. An oily build up on a spark plug will cause the spark plug to misfire.

What causes an engine to surging when accelerating?
Vacuum leaks can cause car surging when accelerating on engines with either a Mass Air Flow system (MAF) or Manifold Air Pressure (MAP) system. Regarding engine surging while cruising, it depends on the type of fuel injection system. An internal combustion engine needs a mixture of air and fuel to create a combustion.
What makes a 91 Chevy surging at idle?
My father in law’s ’91 Chevy was running poorly, so we put new plugs, wires, cap and rotor on it, and it’s running better, but it it still surging at idle. It basically almost dies out, and then surges back to life (probably a little higher than normal idle), then repeats continuously until you apply some throttle.
