Here in California, we have limits that depend on how old the car is and its weight.
Typically, the newer the car, the lower the limits.

These readings can be used to diagnoss what is wrong with the engine, smog pump, catalitic converter, etc.

Here is some more info...

Well it is Drive Green so it must be good.

VET limits pre-2007:
CO%: 4.5
HC ppm: 1200
Testing is at idle & 2500 RPM static.

Should be easy to pass, as even a Datsun 1200, older than your car, was 1.5% CO. Those other figures like lambda are recorded, but there is no test to fail.

I have heard of no other place in the world that is testing 1974 vehicles. Even California only tests 1975 and newer vehicles.

Hi DD

Are they considering date of manufacturing or date of first registration ?

Thanks

Neither date of manufacturer, nor date of registration. Here in USA, everything goes by Model Year.
