So my clock is at 241,000 miles but just about everything on her is new. I have a slightly rough idle off and on, it's a bit more pronounced with the A/C on. Does anyone have a simple fix? I was tossing around a T/B clean, dropping some injector cleaner in the tank, and filling up at Shell. Also, going to toss on some new plugs, cap, rotor, and maybe wires. Anything else I should peek at? It's not bad or missing, just like a stutter here and there. I know I know, picky. Should I entertain an MSD system?
