Hi, Scotty. I have a Honda Civic LX 2009 standard transmission with 176,900 miles and check engine light comes on and off at times: Codes P0300, P0302, P0303. The car starts and runs but if feels like hickups (pulling and pushing) and vibrations coming from the engine when shift 2nd and 3rd gear and loss of power. Changed the spark plugs, 4 ignition coils, pcv valve, oxygen sensor downstream, mass airflow sensor and air filter. What could it be?

Fire some more parts at it!
Or read the FAQ and try some troubleshooting.
