Hello there.
The P0300 engine code indicates that misfiring happens when insufficient fuel is burned or when the spark plug gets damaged. In addition, it can damage your car's catalytic converter in extreme conditions. Our company has an article about this particular code (P0300). To find out more, click here.
Along with the spark plugs and wires, other components that require inspection include the EGR valves and tubes, head gaskets (leaks), camshaft sensors, airflow sensors, oxygen sensors, and throttle position sensors. We advise getting the car examined by a licensed mechanic for a real-time diagnosis to ascertain which part or parts require replacement.

A misfire in multiple cylinders of your 2005 Kia Sportage 2.7L V6, along with the presence of oil in the intake manifold, can indicate a few potential issues. Here are some possible causes of the problem:
Faulty ignition coil(s): The ignition coil is responsible for providing the spark that ignites the fuel in the cylinders. A faulty ignition coil can cause a misfire in one or multiple cylinders. If you haven't replaced the ignition coils yet, it's worth checking them for any signs of damage or wear.
Clogged fuel injectors: If the fuel injectors are clogged or not delivering fuel properly, it can cause a misfire in one or multiple cylinders. You've checked the fuel injectors, but it's possible that they're not delivering fuel at the correct pressure or volume.
Vacuum leaks: A vacuum leak can cause air to enter the engine without going through the air intake, which can result in a lean air-fuel mixture and misfires. Check for any cracked or damaged hoses or gaskets in the intake manifold or vacuum lines.
Low compression: Low compression in one or multiple cylinders can cause a misfire. This can be caused by worn piston rings, damaged valves or valve seats, or a blown head gasket.
The presence of oil in the intake manifold suggests that there may be a problem with the PCV valve or breather system. Excessive oil in the intake manifold can cause a misfire and other engine performance issues. Check the PCV valve and breather system for any signs of blockage or damage.
It's recommended to take your vehicle to a qualified mechanic for a more thorough diagnosis. They can perform a compression test and other diagnostic tests to identify the root cause of the problem.
