I have replaced my plugs in my truck and it worked for a while, but everytime it rains it is missing tremendously. It's gotten worse to me. First it was on when it shifted to like the 3rd gear but now when i start it its idling funny and its missing really bad. I need a solution please. I am to the point ot where I want to get rid of it. The only reason I kept it is because its paid for and it was my grandfathers vehicle. PLEASE HELP!!!!
