The first code, P0354 is for a coil primary circuit failure. May be a bad coil. Codes P0304 and P0308 are misfire codes for cylinder number 4 and 8. May be the coil issue causing it. The code P2310 and P13A-00 are vehicle manufacturer specific and cannot be answered unless a vehicle and year is known. If you want to have the diagnostics for your Check Engine Light verified, a mechanic from YourMechanic, can come to your home or office to inspect your car’s rough idling issue and make any other repairs that are needed.
