Tune up gone wrong?
I had a tune up today on my 93 chevy
silverado. New spark plugs, oil filter, and
ignition wires. It was running great before
all these "updates" now my truck shakes in
idle, and it sounds as if it wants to quit
running. The batter needle on my gage goes
up and down when idle. And I have even
slower acceleration speed than before. Ijust
paid good money for these fixes, what is
wrong now? Meinike screwed up, or what?
