I have a '97 Civic with a D16 that I autocross. It has 84K miles on it and I'm not sure if it's had any tuneups (I bought it 6 months ago). What, if anything, should I do for a 'tune up'? I've been thinking about flushing all the fluids (radiator, oil, mtf), but do I need to worry about checking the valves, timing, etc? I have all the tools I need to do what I need to, but should I take it to a dealer? Please advise...
