I have a 1993 Dodge shadow with a 2.5L motor. It runs poorly right now. I just put a new distributer cap and new spark plug wires on it to hope that they will help. When I first start it up when it hasn't been ran for a couple of hours it has a very rough idle. What should I do to make it run better? Also what are some cheap upgrades to give it more power but keep above 20 mpg?

Well one thing that you could do if your state law allows it is hollow out your cat converter so youget more power and you don't waste hp.
