One of the first things that needs to be replaced to smooth out the engine is the plugs and wires. There is also a chance that a new coil is necessary, but I haven't checked it out completely yet. Is there a consensus on these parts, or is this yet another source of discussion. I'm not looking for anything above and beyond, just a good replacement for some old junk. I figured I'd ask before I went and got something, only to find that something else was the standard. Thanks!
