Heads & p0300 . I am having a problem lately since i swapped my damaged stock heads with other used one`s. codes p0300 & p0200 r there all the time and I can feel the power loss.
my question is it possible that those new heads i put in my car r damaged to? would a bad valves show those DTC`s.
also I would like to know what other factors makes those codes appear. I changed ( plugs ,wires, injectors) but still nothing.
Thanks.

to start I would log cylinder misfires on each cylinder, and then see which are more prevelent/higher numbers than others... then check the Spark plug and wires (may be possible that under load it's not getting a good spark, but normal driving it's sparking enough to burn the fuel up w/out setting a rich code)
