I just got this truck, 3 days new to me, and had been running great! First day, sunny, warm and dry, ran great. The second day raining lightly and I noticed that my truck wasn't idling right, but got me from point a-b. Today it has rained alot and I've gone through a few larger puddles and the engine has died on me. I had to get towed home as its still raining and the engine compartment is still wet. I've checked the spark plugs and they seem dry, fine. Where would I begin to rule out things other than this?
Thanks J
