Literally, let the engine run for 2 long seconds or less. Take the temp gun and see which pipe stayed cold? That's a compression problem, you have spark an it's dripping fuel. Get it? You met 3 start variables and it shows you have both, but were is C in all this?
Misfire = How dirty is the A/C element to cause a too rich condition and misfire the plugs. You figure you have 2 coils and if the one coil can spark the one plug, there is spark out that other side of the coil or it won't fire one? No, it's a wire in and wire out jobber. It fails, both inside fail. Make sense?
