Question type: Maintenance & Repair

I got a PO304 code. I've replaced the injectors and spark plugs and still runs the same.

4 Answers


PO304 is a misfire code for cylinder #4. Try moving the ignition coils to see if the code move to another cylinder ex PO302 is Cyl #2. before purchasing a new ignition coil.

If that doesn't work, compression test the cylinder. If it's very low or zero it's a valve problem. HTH. -Jim


Thanks. I forgot to describe that the problem would happen intermittently. I went back and took a look at the spark plug wires, which seemed okay. Suspecting that was the problem, I replaced them.... Problem solved.
