300 is a random missfire. 316 is a missfire at start up under 1000 rpm. the 316 is most like a failed coil. how long has it been since you had a tune up?? i would start with a set of plugs and coils. beyond that, you need a shop to check compression and vacuum leaks as well as the injectors. Roy

The codes are misfire usually plugs and coils are the cause. Given the jump start was done correctly, that shouldn't be of any issue.

for your code. try If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors. Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open
