I have a 2002 Diamanté VR-X. I was having an issue with it not starting when it rained out. Since I just bought it and no maintenance had been done, I decided to replace plugs, wires, cap, and rotor. When I start it now, it idles really rough but now has a bad knock. I just switched everything back to the old parts and it still does it. I don't know if wires are on wrong or what but I'm stuck. Does anyone have a suggestion or know the firing order and cylinder numbers? Thanks in advance.
