How do I fix misfiring
My car is sputtering on acceleration and even on idle. P0300 code per computer controller.
2016 Nissan Versa Note.. 4cyl
Tune up was done a few months ago.. Spark plugs, wires , etc..
Catalytic converter replaced recently and then P0300 starting to present. Vacuum seals on intake manifold? Any other possibilities? Fuel Pump or Filter maybe?
Alot of things can cause a misfire, lack of fuel, bad data to the computer such as a faulty MAF, corrosion on a coil, headgasket. Are you losing coolant, and do you have anyway to look at some live data?
I double-checked the download at Advanced Auto, The p0300 is the only code being pulled. No other codes specifically pointing to another issue. No leaks that I can detect. I cannot look at live data since I don't have the equipment. When the catalytic converter was replaced it was pretty much a wreck. Pieces jangling inside when he shook it. Don't think that is supposed to happen. If it is a distributer cap or vacuum seal would there be another more specific code thrown back?

engine has probably been misfiring for some time. See the FAQ for troubleshooting tests.
Probably a bad coil. There are no plug wires.

All it takes is a $50 scan tool. Check the FAQ for recommendations.
