It would drop a cylinder at all loads and speeds one moment, then it would =
run fine everywhere.

  Probably #4 coil.  How did it behave?  Started missing only under boost b=
ut would cruise OK and then slowly get worse?

    I've got a problem with my 95.5 S6.  Here's the setup:
      a.. In Feb I had a POS channel go bad.  I swapped over the wires to u=
se the spare channel and things were fine.
      b.. A few weeks later came another misfire.  When I went to diagnose =
it the motor went back to hitting on all 5 again, so I couldn't figure whic=
h cylinder had the problem.  I figured I was losing another POS channel, so=
 I bought a new one from a lister.
      c.. Over the past few months the misfire would pop up again, then qui=
ckly disappear, usually after I turned the car off and then started it back=
 up again.  Like running a Microsoft based car.
      d.. Yesterday the misfire came, but this time it didn't leave.  Using=
 the remove-the-fuel-injector-plug method I determined it was #4.  That mad=
e sense, since the POS for #4 was the one that had the bad channel from Feb=
.  I found the new POS I'd purchased months ago and popped it in, and guess=
 what?  No change!  I swapped out the other POS just to be sure, again no c=
hange.  Darn.
      e.. Checked the spark plugs, they were all tight.  I changed the #4 s=
park plug and the miss was still there.
    Soooo, what's the next likely place to look?

    Thanks in advance,

    Phil
