Tuning

I understand, but what's wrong with doing a little research before hand. I've been away from having to do much on a car for a while now. Everything that I buy and pretty much do I check it out first. And who knows, I just maybe happy with the way it is. I like to be prepared if for some reason the guy ahead of me was a shade tree mechanic or a would be tuner. I understand and agree with getting the car first and not putting the cart in front of the horse.
Nothing wrong with asking some questions especially if you have an issue you are tying to solve. There are hundreds of threads about the basic questions you are asking about. It's things you need to learn about without us repeating it for the hundredth time. Without a car for us to diagnose, we are literally spinning our wheels trying to answer questions to solve problems that don't exist on a car that hasn't been bought yet. Just sayin'
