I had a guy at the local AutoZone pull codes on my 2000 v-6 wagon. I've got a couple O2 sensors out and a #3 misfire. I figure I should change the plugs. The problem is I can't even see the plugs. What's involved? I looked at a Hane's manual for the car, but it was no help glad I didn't buy it. Does anyone know where to find instructions online? I'm not willing to pay Saturn $xxx to change the plugs if I don't have to. I know I'm gonna have to buy a bunch of those fancy star shaped sockets, what are those even called? Are there plug wires that can be replaced or does each plug have its own coil? Oh, and if you've got better suggestions than replacing the plugs let me know. The engine lopes when in idle either with or without being in gear. Well thanks for your input, Paul
