I have a P0300 Random/Multiple Cylinder Misfire Detected. I also have a P0420 Catalyst System Efficiency Below Threshold (Bank 1). I would like someone to help me out with these two issues because I have a bunch of mechanic shops in my area that obviously can't fix a flat tires correctly. Please help me out with this. Thank you.
