Hello,

I suppose you’re talking about P0301 and P0304? It could be several things:
Bad spark plugs, bad wire, problem with your coil pack, low compression, defective O2 sensor, vacuum leak, wrong fuel pressure, bad EGR, wrong timing, bad MAF sensor, bad TPS sensor, bad CPS sensor.
If you never replaced your plugs and wires, this is probably the first thing you should check.
