Subject: [s-cars] eggs

[Mike Platt]

The cats went because the thermostat was wide open
most of the time. My engine never really warmed up so,
it ran rich. Gage was near the cold mark all the time.
I found out later that I should have changed it in
January instead of April. You know, too cold to work
on the car so wait till it warms up. The thermostat on
the V6 cars was behind the water pump which was behind
the timing belt. yadda,yadda,yadda. Anyway, I waited
and that's what I feel led to their destruction.
