I will ocassionally get a CEL 68, but I dont know what that is. I dont see any information on it. Its a 94 integra GSR with not other problems. The car will hick-up, then throw the CEL. It is usually once every couple of months. When I turn the car off the back on, it is gone, so I know its not that important of a CEL. What are some possibilities that would cause this?
