As usual, not even 2 weeks left and a problem arises.



I heard a rattling noise briefly on the way home last night, kinda like a rocker loosened up. Today I find that #6 plug lost it's porcelain. I need to find out what's going on. Of all the problems I've had, every last one has been on the driver side bank.



The motor has been making no audible complaints about the tune. My 02 sensor says it's got enough fuel. I've never been able to get the plugs to be tan. I can get it so the fuel can be smelled from the exhaust and they'll still be white. I've heard that's just the way new gas is.

Everyone I talk to says detonation causes plugs to loose the porcelain. My exhaust is either too loud for me to hear it, or it's not loud detonation, or it's something else. I don't hear or feel anything like detonation when I drive it.



Some of the plugs do have colors- grays or reds. Here are pictures, starting with the "bad" bank. What do they mean?
