take your automobile to your local specialist and it will probably be a blocked drain or perished seal on your automobile

Try using a dielectric grease at the plug wire connections to keep moisture out. If your car has a distributor cap seal or O-ring make sure it is in good shape. http://www.amazon.com/Permatex-22058- Dielectric-Tune-Up- Grease/dp/B000AL8VD2%3Fpsc%3D1%26SubscriptionId%3D06K MPSHEDSXXQMQVT482%26tag%3Daskcom05- 20%26linkCode%3Dxm2%26camp%3D2025%26creative%3D1659 53%26creativeASIN%3DB000AL8VD2
