Can be a defective plug wire, burnt valve, cracked head, or blown head gasket. Replace the spark plug wires. If you still have the miss, have a compression test run on all cylinders. Low compression on cylinder #4 indicates a burnt valve, cracked head, or blown head gasket.

What is Service engine soon code po304?
It is telling you that a misfire is detected in cylinder number 4. To troubleshoot this the easiest thing to do is take the coil pack from number 4 and exchange it with number 3. Reset the light and run the vehicle. When the light comes on again see if the code is po303. If it is you have a bad coil. If it still says po304 you probably have a bad spark plug or plug boot. Good luck to you.

Check the sparks, if not it could be the rocker arms or coils in the engine, get a compression tester, test the compression of the cylinder, if theres no compression. throw a capfull of oil down the hole where the spark plug goes in and redo the test, if the compression goes up, somethings wrong wit the piston and the ring, if not check the cylinder head
