Well Scott, I would not say they are missing him.

Rodney

the village is definatly not missing their idiot scott, that is why he is
here. they don't want him back.

has anyone else noticed that since we got our own private resident a.shole,
that the number of posts has risen from around 10 per day to around 40-50
per day???

Wouldn't want to have bet on this but after a fuel filter, two new coils
(one to be returned after the check clears) a lot of cussing and a
couple skinned knuckles I replace the plugs and it fixed the problem.
The old plugs were Bosch Platinum and I can't tell anything from a
visual but maybe I can test them somewhere.  As far as burn goes they
look perfect (always have with this engine) and I just put them in a
couple months or so back just before a smog check.  Is this rare?  Seems so.

read codes and preform a power balance test

Probably not, unless it is a true miss.  Best approach is what Tom
suggested to you.

 The "computer" will only identify the cylinder(s) that are not firing, either
through a misfire code or a power balance test. Once the "bad" cylinder(s) is
identified, you will have to check for compression, spark, and fuel supply to that
cylinder.

 If the miss started suddenly, the problem is likely a dead spark plug, a dead coil,
 or a dead injector. Another possibility, if the miss developed over a period of
time, is a spark plug wire arcing through the spark plug boot.

You can identify the missing cylinder by unplugging the electrical connector on the
injectors one by one with the engine running. You will notice an RPM drop or a
worsening miss. If you find one that makes no difference, that's your dead cylinder.
 Pull your spark plug wires off of the spark plugs and check for oil on the boots and
for signs of arcing, usually grey spots and pinholes on the side of the boots or grey
pencil like lines out of the boot opening. If there is oil on the boots, the valve
cover seals are leaking and will need replaced along with the wires.
 Remove the spark plugs and look at them. The plug in the dead cylinder may look
either cleaner or dirtier than the rest. You can rule out the spark plugs by
replacement, they are inexpensive and probably needed anyway. About $16 max.
 You can test for spark at each wire with an inexpensive Spark Tester. It looks like
a spark plug with a clip on the side. No spark points to a dead coil pack. (This will
usually cause a miss on 2 cylinders).
 If the plug wire and spark plug on the "bad" cylinder are ok, and there is spark
present, you likely have a dead injector.
 The above steps should locate your miss. Low compression will cause a miss, but it
is uncommon. If you have access to a compression tester and know how to use it, it
can't hurt to check. Another possibility is a PCM not triggering a section of a coil
or an injector, again this is not common.
