Having problems with your 1994 GMC Sierra ?
I have a '94 sierra 5.7, I changed my spark plugs recently they weren't all in that great a shape, mainly just worn out. There is only one terminal (#2) on my distributor cap which was corroded bad when I changed it out, and the associated plug wire (#2) was rusted & corroded bad too. I'm going to guess everything on this truck are probably still factory parts. What would cause just the one cylinder's (#2) associated ignition parts to corrode so badly?
