Thanks Steven -
Those are some good smog numbers.
I'll look into the injectors. They've never been serviced in 23 years ......
My shop says that any tune up or injector issues would show up in the test results.
They say the problem is most likely my brand new catalytic converter. I'm not sure if I believe this, but I am looking into it.
Do you recall what brand your converter is or where you got it?
Thanks,
Walter

Walter,I think high NOx is due to running too lean, which raises combustion temps.CO% = 0.04 could be an indication of too lean as well.Perhaps you need to clean your fuel injectors. Both injectors on each bankare needed to supply the proper fuel mix to each cylinder. One weak fuelinjector will cause the engine to run lean on that side w/o much symptom inmy experience.Take out the the plugs and see if they are a toasty brown color or white onthe insulator. If white => too lean. You can get rebuilt injectors from theonline suppliers list. I tried a local machine shop for a good cleaning andwas not happy. You need someone who really understands injectors to get asatisfactory result.The new catalytic converter also needs to be approved for CA as well,specifically to achieve lower NOx.My last SMOG check on my '84 1.9 yielded a 15 mph CO% of .12 and NOx of 116and a 25 mph CO% of .2 and NOx of 81. I was once a gross polluter.BTW: once you are labeled a gross polluter in CA, you can get the state topay for some or all of the repairs. You just need to talk to an approvedrepair shop, no other requirement.Not an expert,good luckSteven
