I just changed my plugs and wires today. The Service Engine Soon light is off. I am not a mechanic and honestly, I don't think you have to be one. It is not complicated, but it is difficult. I did go ahead and change my ignition rotor and distributor cap. I am glad I gave this a shot, but I probably wouldn't try it again. It is now vibrating quite a bit and I need to figure this one out. I hope this helps you...

I have a 2002 Chevy Impala and wonder what damage can a cylinder misfire cause?

A cylinder misfire by itself shouldn't cause to much damage, but if you drive it while it's misfiring, it will cause a strain on the rst of the engine because you are going to be pulling the same weight with only 5 cylinders. The car will work harder, get hotter, etc. My suggestion is definitely to figure out the problem before driving the car anywhere long distance. A couple short trips is probably not going to cause undue damage, but if you have a way to drive a different car until you get the misfire fixed, I would hold off on even the couple short trips.
