			Hey! I found something really odd, I have 98 323is and while I was looking around today I saw that it only has 2 oxygen sensors! one pre cat and one post, the bungs on the manifolds are blocked with bolts. Is this something normal? I heard of a few other cars like this here in the US.

			The vehicle should have four, two per engine back. Are the wiring harnesses tucked away to the side? They would be near the connectors for the other oxygen sensors.
