Yes it's bad, will lead to stopping up your catalytic converter
Do you have a P0306 misfire code?
Remove the spark plug #6 and compare to the color charge below.
Do a compression test on all cylinders and check the values.
The highest and the lowest psi should be within 10%.

SOURCE: miss fire on #6 cylinder. Potential causes. Which
The #6 cylinder is the last cylinder on the right side while you stand in front of the vehicle. Firing order is 1 - 6 - 5 - 4 - 3 - 2. Potential cause and best case scenario is you have a defective spark plug causing improper ignition. Another scenario is the #6 coil pack is defective. If you have not replaced the spark plugs (30,000 mile intervals), then the issue may be just the spark plug(s).
