Hi Guys

got a 2010 fox in the work shop with a intermittent miss fire on No 3 cylinder.

Customer changed plugs and 3 ignition coils

No other fault codes other than miss fire No3 cyl

If you pull hard throught 2Nd to 3Rd just under red line eml flashes on and goes off No 3 completely .

I was thinking it might be an hydraulic lifter holding the valve open
