I am having trouble passing smog with my '84 635. The initial advice was to replace the cat. I did.
It is still having high nox at 15 mph.
I tried adjusting the spring 2 notches on the AFM to riches it up. Now 25 mph doesn't pass because too rich, and 15 mph is still too lean.
Car just had a tuneup and the camshaft was worn.
What else should I look at?
(The papers have it as a 3.2 liter because it is '84. But it is a 3.5 liter Euro.)
