I would recommend getting the code(s). Even though the vehicle feels like it's running okay, the ECU is telling you there is an issue somewhere. Whatever the problem is, it could potentially cause other damage to engine components or decrease gas mileage if not corrected.
Ok will do and post what outcome is on the codes it generates thanks

take that code to your local parts store of mechanic they will tell you what the problem is and how to trouble shoot
Refer to the following link for symptoms/solutions. Basically, A P0304 code indicates that the fuel in cylinder #4 is not igniting or combustion is inadequate. this could result in raw fuel entering the exhaust manifold and finding it's way to the catalytic converter which could cause problems. Or there may be a fuel delivery or valve issue for that particular cylinder. http://www.obd-codes.com/p0304
