I have a check engine light on, and when scanned the code tossed is p0303 and p305 On April i changed all the spark plugs and injectors. Suv doesn't have any weird noise, doesn't have resistance doing trails, is not getting hot either but still have that misfire code. Battery level is telling 13.8V which i understand is good. Do spark plugs dont last that long and need replacement? What else can make this troubleshooting? Autozone doesn't seem helpful they told me "they dont know"
