im getting code p2305 & p0302, replaced spark plug & coil on plug for cyclinder 2, also replaced harness for injectors & coil on plugs. after all that the code is still active & wont clear , you can definitely feel the motor misfiring from inside the vehicle. before i jump in and take apart the rest of the harness , does anyone have any other suggestions. ? the pcm has already been replaced months ago for previous issues.
