Going from the malfunction codes you have a problem with the ignition coil .
this will cause the P0300 and P0304 which is a Misfire code and grand misfire on 4th cylinder .
I would start by doing a ignition tune up first by replacing spark plugs and plug wires .
still getting the P0351 then i would check the wiring to the coil if good replace the coil .
Most case these coils point to the coil and coil wires to the plugs .
Do this and get back to med with this issue then please get back to me with the reply box below .After rating there is no further cost for any other question relating this issue .Kind regards Greg
