Hi guys. I just spent the last 2 days driving back from Colorado to Texas with my new to me 1989 Carrera 4. It did splendid and I got nearly 1000 miles of time to start meeting my new companion. I made a stop along the way and with the engine running removed the oil filler cap (expecting to find the dip stick in there like my 3.2). I quickly found it moved to it's own location in the 3.6L, but I was confused by the behavior of the engine. There was no stumble or rpm drop when I removed the filler cap. Does the 3.6 not drop rpm when the filler cap is removed, or do I have a vacuum leak somewhere else I'm not aware of.
Oh, and a pic.
