Crazy missfire

[VW-will]

Hey guys, bm has started too have some crazy misfire recently, it was only slighty at a certain rev 3k, changed the afm as I was recommended by some1, now it's all the time sounds like it's running on 5, all compressions good, plugs injectors etc, smells really fuely..... Any ideas?

Pull the rocker cover off and check that you haven't snapped one of the rockers. Sounds like what happened to me a while back.

Mate check distributor and rotor arm i had exactly this same problem
I did change rotor arm and everything back to normal

It was injectors, some dodgy fuel made 1 of them like a tap, in turn melted a plug... All sorted now
