I would start with a cylinder compression test to see if one or more are low on compression compared to the rest.If one or more are found to be low on compression this can be caused by cylinder wall damage,valve damage in the cylinder heads,piston or piston ring damage.The engine will need a leak down test from there on each cylinder with low compression to help with locating the fault then the engine taken apart for inspection and repair.If the compression test is found o.k. let me know so we can continue.
