teh codes you are talking about is one of your injectors has an open circuit, 0300 is multiple misfire, and 141 is O2 sensor bank 1position2 isn't working. Take this to a pro as all 3 codes may be eliminated by fixing the open in the injector. That is what is probably causing all of these to go on. But it could be another problem as well.
