Recently my 370 threw a P0300 code. My cars about 11 years old so I figured I needed new spark plugs or coils. I proceeded to buy new coils and plugs and cleared the code but then the code came back the next day. After looking on the forum a little somebody suggested to clean the throttle body’s so I did, cleared the code, and then it came back. A little side note the only thing i’ve done to this car is install a Tomei catback exhaust ( I know it’s basic ) and replace plugs and coils. I’ve still not found the root to this P0300 code. Any help please?
