When I started my car up after we returned from CAA-RME the engine was ticking quite loudly at below 3000 rpm. First of all it had gotten about 1 quart low on oil, filled it - still ticking. I searched the forum and read about the injectors ticking at low rmp \ idle. It would go away at faster rpm's. So I figured that injector tick was what I was hearing. Today we took it to the movies and the tick is gone. And that darn a\c fan comes on every time without tapping on it since we've been back - go figure.
