[s-cars] Short term rough idle - follow-up

[james McCarthy]

Bob,
Still sound's exactly like my HG failure...
Before firing it up first thing in the am pull the plugs (or at least #3 and stick a long q-tip into hole and touch the piston.  When I did this I got coolant.  The spark plug showed no signs of being washed and looked no different that the others.  Also hows the coolant look??? mine started slowly changing color but this didn't start until several days into the symptoms.
