What to do if your car has a p0306 code?
Use FIXD to scan your vehicle to verify P0306 is the only code present. If other codes are present, they must be addressed first. Check for loose connectors at the ignition coils or for damaged wiring (specifically cylinder 6). Look for loose engine ground wires as well. These can cause random misfire conditions.
What makes a p0306 cylinder 6 misfire severe?
Once the misfire becomes more consistent and severe, a P0306 will be stored and constant MIL illumination will occur. Conditions which promote storage of a P0306 are likely to cause catalytic converter and/or engine damage. This code should be classified as severe. Rough or unstable feeling from engine (at idle or under light acceleration)
What does it mean when spark plug is p0304?
If the misfire moved to cylinder number 4 (P0304), then you have determined that the coil pack is faulty and needs replacement. You can do the same test with the spark plug, i.e., move cylinder 6 plug to say cylinder 3 and if the misfire is now P0303 then the plugs are at fault.
