zone legend davidt popped over earlier had a look, he doesnt think its a piston and its nothing major, just a missfire something in the ignition area, i pray so !!

I'm not an expert if an engine is breathing it doesn't suck when you remove the cap it blows and the m20s do suck as they run a vacum system or something like that the revs should drop when you remove the cap
