2003 grand prix gt. Will take me an hour to get the damn thing running on wet days. Does not want to start. Any other time its fine. When i do get it started it studders and misfires till it has a good run. Right now it isnt on the road because i have a second car, so its been sitting for 2 months getting the odd fire up. I want to get it back on the road though! I had a cracked coil which i replaced. Took all the other coils off and inspected them and they seem fine. Pulled all spark plugs, seem good. Wires seem to be ok. Anything that could be a popular cause with these cars that i should be looking at?
