The bad smell is not like rotten eggs, but more like a rich mixture. It is the kind of exhaust smell that permeates your clothing and doesn't go away until you take a shower. i have had the car for about 2 years (test pipe since I got it) and it has just recently (3 or 4 months) started smelling bad. As for plug wires and idle, the wires are probably original and I have a slightly rough idle as well. I use top quality Chevron from a new station in all my cars. No problem with the others.
Any other thoughts? I probably just need to adjust the valves, change the O2 sensor and plug wires and get a good tune up.
