I have a 2002 z06 with 50,000mi. on it. The car runs very well with no codes. Sometimes when i sit in traffic at an idle the engine seems like it starts to run a little bit rougher...doesnt try to stall or anything. Its just a little rougher than usual. All of the gauges are normal...also there is a slight valve tap sound, not when the car is first started but maybe a minute after. Anything i should be concerned about? No smoke, runs fine 99.9 percent of the time and is quick as hell. Also I was wondering when i should start thinking about tuning it up...plugs, sensors, filter, belts, etc. thanks everyone...great website! :thumbsup:
