The 300 seems to be popular here lately, and mine runs pretty good. However, there's one thing that I'm a little stumped over. The number 8 spark plug reads much leaner than the others...it's white where the others are dark tan. This is with two sets of plugs...could the PCV valve being over that cylinder cause this? Is this common on the 300? The car idles too well to really have a vacuum leak, and I have 18 inches of vacuum. Any ideas? Am I getting a little nitpicky with my engine? Maybe I should do what 99% of people do and never pull the plugs! p Thanks! Aaron
