Hello Scotty,

I have a 2004 Toyota Camry I have this code showing I have cyclinder 1 misfiring at first I though it was my Ignition coils so I changed the faulty one but his code still appears. Any idea why?

code: PO300

300 is a random misfire. P0301 would be a cylinder 1 misfire. P0300s can be absolute cows to fix, though on those often a bad or dirty maf sensor, or diry fuel injectors that need serious cleaning
