My '96 has a barely audible misfire, not when cold, and not when hot and been running a while, but usually during the warm-up. My #2 plug, after a while, will get white and fuzzy, although nowhere near as bad as yours. I use Champ Coppers in it, changing every 30k miles, and during that time, I'll pull it once or twice and clean it. The other five are barely even dirty. Also, every second or third oil change, I'll throw a can of BG44K into the fuel tank, and it makes the misfire go away for a while. I bought the car with 104k, just turned 180k, and it actually runs better than it did seven years ago.
I once put Autolite platinums from Walmart in my '92, and it ran great. At the next 30k tune-up, I pulled them out, and they looked so good, I put 'em back in for another 30k. Next tune-up, they still looked great, but with 60k on them, I figured it was time to go. Now it's got Champ Coppers in it, but it still runs great, at 205k. My son once put Bosch plugs in his '95, and it ran like crap. I told him to try Champs, that's what most recommend on
, and, of course, he doubted me. But a day or two of sputtering, he figured he'd try the Champions. Cleared it right up! I've never seen that in forty years or wrenchin' on cars.
Then there's our '04 Outback. I had the head gaskets done at 90k, one was pissing coolant, the other weeping oil. They all succumb to it, and it's probably the only thing that goes wrong with them. Anyway, I had Autolite Platinums in it, and at 90k it was due for plugs. Tapping like crazy, and when I pulled them out, the center electrodes were GONE, and the ground electrodes were about half-gone. Tried new Bosch plugs, tapping like crazy again. Looked up OEM, and it had come with NGK plugs. Got those, and it continued to tap, although not as bad. Went on the NGK website, looked up plugs one heat range cooler, and the car hasn't tapped since.
Maybe try the two offending plugs in a hotter heat range. I've read that the hotter the plug, the less likely it may foul. Although, the black one seems to be disappearing!
