He said that he dried up the water down around the plug before he pulled them out but some may have gotten in. What kind of problems would it cause if a little water got in there? His plug wires are stock I think. I mentioned to him that he might replace them with better ones. It's been running fairly good for a few months. How long would it take for water damage to have an affect? The engine sounds the same, it just doesn't have as good of performance. He also recently took out the MAF, cleaned it with alcohol and put it back in. We said the wires were filthy but cleaning it didn't make any noticeable improvement.
