recently my engine start to miss fire after rain, i know it's something to do with the spark plug wires.. i am just wondering if i can just spray some WD40 all around the wires and onto the rotor cap to prevent the moistures get in
thanks

 

you probably have a pin hole in one of your wires so if you get new ones than you won't need to make anything water resistant

 

did the check engine light come on. If it came on did it flash. I would just remove the wires spray some wd 40 on the wires and remove the dizzy cap spray some wd 40 let dry then restall everything to see what happens

 

yep dry out the dizzy water is getting in there
