I just wanted to follow up on this old note of mine.  I had an =
inspection done by a local shop in May 2011 and therefore did not think =
the plugs would be a high probability item.   I've had hard starting and =
idle problems all summer.   When a plug stopped firing yesterday I =
pulled all of them and the gaps were set to something less than 0.010 on =
10/12 plugs.  There were some balls of (lead?) deep into some of the =
plugs, whitish deposits on the insides and some of the gaps were shorted =
of course.     These are massives, RHB32E on the IO-550N.  These plugs =
had about 70 hours since the "condition inspection".  I forgot to check =
the resistance that one owner wrote about but I did test them under =
pressure and all fired properly after cleaning. =20

As suggested here, I did not go after the injectors. =20
