Ok, I need some input. I just got a 2002 XR4 and was doing some routine maintenance. I pulled the spark plug, (which was a b@#$%), but then realized that the area around the hole was dirty. So rather than putting the plug back in to clean around it, which is what I probably should have done, I used my air compressor to blow out the dirt! Not thinking (obviously) and possibly blew some dirt particles down into the plug hole creating possible problem for the piston? And ideas or ways to clean this out? I was thinking of attaching a small rubber tube to my shopvac to get down in the hole????
