In most cases some type of ignition component failure,
Personally I would say seldom a spark plug,go with ignition
coils or coil packs or modules,depending on what your engines
system has.
Misfires are not always cut & dry, as to the cylinder codes
So I wouldn't start replacing parts,have it proper diagnosed
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).

Check the codes, if there is a misfire it may tell you which cylinder(s) is misfiring. The coils fail, and make sure to use Volvo spark plugs!

SOURCE: cylinder not firing
Have you verified that you are getting spark at the plug when the engine turns over? To do this you can remove the spark plug and insert it into the end of the plug wire. Set the electrode against something metal on the engine. Crank the engine and watch for spark. If you get spark, then you can start thinking about timing, cylinder, fuel problems. If you don't get spark, think about distributor cap/rotor or wire problem.

power not reaching cylinder 1 ignition coil. check electrical connections and wiring for any damage. test for power and ground at cylinder 1.
hope this helps.

Sounds like a blown head gasket,bad valves or bad rings.If this is the only cylinder affected then the head gasket is more than likely the problem.
