Omega A 24V stutters, runs like a 5-cylinder engine !!!!

My omni stutters while accelerating. It’s as if it only runs on 5 pots. Jumps in the cold as well as in the warm condition always. LMM changed, candles all deer brown. Fing just started 14 days ago, while driving light unbalanced.(Motorshake) Something of the gas and good…again some gas and there it was. Days later everything was fine again…. Now when idle it was easier to run round and giving gas as if it was a 5-cylinder engine, with lots of gas giving like a diesel. With slow gas giving a little better. M otor sounds good, but also accelerates……good. Petrol pump, filter and tank new. As well as all gasoline hoses.
