Hi All

Have seen this on an unrestored car…does anybody have anymore details…? I assume the 022 refers to the 1.7L but what about the other number?

Any insight would be appreciated…thanks

I wonder if (?) the other letters denote the second-party supplier/vendor. Bosch did that with lots of their stuff (condensers, etc) though with additional numbers. Another wrench to our brains! (IMG:style_emoticons/default/blink.gif)

could be. those 2.0L throttle bodies have LUS stamped on them - whatever that means (IMG:style_emoticons/default/headbang.gif) ?

i found US vehicle emissions standards for the 70s.
there is a difference between Cali and Fed (49 states).
Cali is trying to get NOx down. (but accepts higher CO as a consequence).
its like an interim stage just before cats (cats will drop high CO by converting it to CO2. cal accepts higher CO to lower NOx (main ingredient of smog) for 74 on the way to implementing cats in 75.

74 is a funny year in terms of emissions standards? i've got a feeling that earlier in the 70s it was the target date for cats but lobbying by manufactures resulted in an EPA concession to delay it by a year and phase it across 2 years.
