my car was working great untill i went to subway on the way back home, the car felt like it want to shut off, and the engine soon light start blinking everytime i press on the gas , what do you think wrong with it.
The code P0304 means that you have a misfire at # 4 cylinder, could be a bad spark plug ,or spark plug wire My experience tells me that you have a bad fuel injector at # 4 cylinder.
If your light flashes that means you can cause severe damage to your catalytic converter. The code is for a misfire in cylinder #4 You could have a bad plug, arcing coil boot, or coils themselves may be bad? You could also have a fuel injector that may not be spraying any fuel to the cylinder? Low Engine compression could also cause the cylinder to misfire or low fuel pressure? So take to local repair shop or dealership to have it properly diagnosed. If you keep driving like that you will damage the catalytic converter and that part alone could cost you almost $2000 bucks.
