The codes P0355/P0354 and P0358 are ignition coil driver failures for cylinder s #5, 4 and 8 respectively. Inspect the wiring harness for the drivers side of the engine sine those 3 cylinders are on the drivers side. If the harness is good, have the codes cleared and swap the coils with the ones on the passenger side and see if the codes change to P0351/P0352/P0353 or P0354. If the codes change, then replace those coils. But if the codes do not change, then either the wiring harness or the PCM (Engine Computer) is the problem.
