I have a question for my fellow Impala Enthusiasts...But its kinda tricky. My 96 Runs like a champ most of the time, but lately the car will idle super rough, or sputter when its raining, and sometimes after it rains. It never does this when its dry out, only when its raining or damp??? Does anyone have any comments or suggestions, PLEASE before I start replacing the plugs, wires, water pump(might as well if im replacing the optispark distributor)

Thanks Fellas!

sounds like new optispark and optivent harness time. Might as well check opti electrical connector too. You can get a new one of those if damaged from www.innovativewiring.com. You can get a new vent harness from www.rmsautoparts.com. Last but not least a new Delphi Opti from "Thepartsladi" on ebay for $255 shipped.
