Problem started from putting 89 gas instead of 93 gas and now slow acceleration, skipping, cutting off, and choking out. Already replaced new timing belt, spark plugs and wires, cord, caps & rotors,cam sensors, fuel filters, mass air flow filter and front seal.

Do you have a check engine light On when its happening

Check the fuel pressure with a guage if its within specs if okay try running a fuel injection cleaner and see what happens
