when i turn on my car,it runs for a few seconds and turns off to the battery.I keep trying and it eventually catchs and runs fine after. happens everytime i try to start my car if i havent driven it in the last hour. I checked the mass air flow sensor and valve. checked the air filter, and i know i need new spark plugs which i will be getting this week. my check engine light is on and it says 'cylinder 1 misfire' what could it be?
