Tune up, it must have been a WHILE...

i was finishing that tune up today, and let me tell you, i now know why my car was running rough and making that knocking sound.
im not sure what cylinder number it is, but the very back one on the drivers side, the plug was about to fall out, and the wire was barely sitting on top of the plug, arcing to the exhaust manifold, making a clickity/knocking/tapping sound. it was arcing like, a half inch, at least.
the guy was like "that tapping sound is there sometimes, sometimes not..."
GEE, I WONDER WHY??
im glad im getting this car taken care of, im gaining more and more confidence in it everyday :)
A BODIES FOREVER!
