Lessons still being learned, the gee whiz mechanical testor proved that the
parts I bought were good, great. They managed to get the yellow light of
doom to quit displaying but are concerned, as am I, as to the point that
my truck still has the same problems despite 2 very expensive hours under
the wrench. They did however tell me it wasnt the brain, or the vacuum
lines or wires. Any other clues to the mystery?
