Motor is 84 with 86 fuel injection and electronics with 90+ upper intake/throttle body. I changed the plugs,wires,cap and rotor today because I wasn't sure when the last time they had been changed was. I tried taking pictures of the old plugs but it's tougher than I thaught to capture what they really look like. Anyway number 1 was dark and wet looking on the electrode but not really on the ground, I'm not sure if it's fuel or oil.
#2 and 3 were what I would call normal even though the terminals were so loose they came off with the wires.
#4 was a little wet but only on the electrode not on the insulator like #1.
I expected after replacing everything that it would sound and run great. I haven't taken it on the road yet but running it in the garage it actually sounded a little rougher to me. Tps was recently set and in spec, timing is set, no stored codes. The truck has always smelt on the rich side to me but the tail pipe is clean, not black. What do you guys think?
