Okay I want to start out by saying I'm not tuning my own car so don't be alarmed when I ask rookie questions about tuning. But I've always heard people read the plugs an check the plugs but what are the signs to be looking for when your doing that? What do you look for an what do the signs mean. Thank you for help in advance
