Can't get power at all.. misfire p0303
My car has 65000 miles.
My car has an automatic transmission.
Hi there. The code P0303 means that cylinder number 3 has a misfire. There are three ways that the cylinder number 3 can be misfiring.
Check the spark plug on the cylinder number 3 and see if there is a suffucient amount of spark. If the spark is there and is strong, then check the fuel injector and see if it’s spraying or not by unplugging the injector as the engine is running. If the engine try’s to stumble more, then the fuel injector is working. If there is no change, then the fuel injector is not working. If the spark plug and fuel injector is working, then there could be internal damaged to the cylinder. If you need further assistance with your engine misfiring, then seek out a professional, such as one from Your Mechanic, to help you.
