good evening my name is ***** ***** I will assist
did you change the plugs??? the missfire code for 6 code be the plug or coil.
the 300 code is another issue. I would have the fuel pressure checked. it is common for low fuel pressure to cause this code to come up. it will make the engine run lean and will trigger miss fire codes from lack of fuel
thats completely different system. you would need to give me the code for the system to narrow down the area of failure
thats for the pcm which does not control the stabiltrack system. that is controlled by the abs system. see if a parts store can read any other codes for you
how are you making out
