Hey scotty ,I have a question I have a misfire on cylinder 3 and code p0300.All spark plugs are only 2 months used and Iv only changed 2 coil ignition's the one on cylinder 3 and I'm not sure what else I'm supposed to do ? It still feels the same shaking a lil bit.I went to o'Reilly's and they told me on diagnostic test that it will be spark plugs,ignition coil ,or fuel injector but I'm not sure.
