I just did an engine shampoo yesterday, same as usual, but as soon as i took her out for a spin I noticed that the car was missing. I pulled all the plugs and noticed that there was water and condensation in one of the sparkplug holes. I tried cleaning it off but its still missing. I'm assuming a tiny bit of water may have gotten in when i was rinsing the engine off. Any ideas how to get rid of this problem??
