Roland, the most critical thing is that the O2 sensor system be working
and cycling fast. This is simple to check. I live near you and have the
same smog testing issues with my 3 gasoline Vanagons. I always make
certain the O2 is working well before taking a vehicle in for test and
always pass when it is.

You must look at both the voltage and cycle time of the O2 system. I
have an oscilloscope that I use for this except on 2.1 waterboxers where
I use a Digitool.

Come on over and we can look at yours.
