Hello. 3800 with 165xxx that is starting to give me fits when it is wet out. The last few times when it is, or has been, raining, the car turns and spits like it wants to start, but won't. It acts as if their is water in the fuel. Each time I've put some Heet in the tank and waited 20 minutes or so before trying again. It still sputters, but with the pedal to the floor, it starts, smooths out, and runs fine. Well, now we have the first snow of the year and guess what; no start. I'm waitng for the heet to work it's magic while i type. I'm thinking that the heet provides a hotter burn and therefore a better start. I beleive I'm looking at plugs, wires, and a fuel filter as they are plenty due. Is there a bigger issue that i need to look into? Thanks.
