This is one for all the mech's. Does it seem that we are set up to fail in our job? Ie.. poor part quality, lack of parts, etc.... Last Wednesday I did a "B" pmi on a 4.3 dist shaft was worn, replaced dist did the full tune up. Friday car road called for the ignition module. I installed the parts that were supplied. and yet it is still considered a mechanical road call charged back to me. How can I be held responsible for poor quality of parts that the company bean counters swear are as good OE.
