2010 Dodge Charger 3.5L with engine code P0300

Question

I have 2010 Dodge Charger 3.5L reading code po303. Misfire#3 cylinder and crankshaft, vacuum leak, injector fault, high/low fuel pressure.

Answer 1

You could start by swapping the #3 (which is the problem cylinder) ignition coil with the next coil and clear the code. If the code comes back, check if the code follows the ignition coil. Also, you should consider replacing the spark plugs as well.
