My 1986 vw westfalia vanagon camper failed CA smog. It passed 1 year ago(only 3300 miles since) and I have not noticed any different performance since that time. At idle
%CO2 %O2 Meas HC Meas CO
1987 14.08 0.50 73.0 0 .33

1988 10.90 2.80 242.0 2.34

Should these numbers tell me something about the problem? the 2500rpm #'s were about the same. Meas CO went down to 1.40
Thanks for any help in locating a starting point to diagnose the problem.. CW
