I couldn't want a greater running car with 168000 miles on it.Only problem is that it only runs great when it is dry outside.As soon as it starts to rain the problems begin.I got the Random/Misfire P0300 code but I don't get it on dry days.I will be changing the plugs and wires,but for some reason,I don't think that will solve the problem.Any idea of what it might be?Thanks
