You guys are breaking my heart. It's just getting to be good driving weather here! Topped 85 today, but with a little bit of breeze. Same thing tomorrow. They say we might get a tiny bit of rain next week (and a high of 67), but I don't believe it.
Found part of the reason my TR3 doesn't want to idle smoothly. All four of the Bosch Platinum plugs are apparently broken inside the ceramic, but the only symptom is that the center electrode was sticking out of the ceramic. One plug was almost (but not quite) closed completely; the actual gap had to be under .010"! Put in a set of Champion conventional plugs and it's much happier.
