AFR was 13.8 and 13.7 from a display screen but not on print out.

New Maf, less than 500 miles on legal cat (but several years old). Not the freshest gas, but some was fresh.

Smog guy says when all three gases fail, usually a cat issue. I noticed a bit of HC smell while the car was idling prior to testing, didn't smell normal.

I'm a "little" scatter brained, which means I am not 100% sure which brain or chips I have in the car right now. Could be Euro, could be US with US chips or US with modified Euro chips.

Magnaflow Calif catalog lists single TWC 36014 (with a couple variations on inlet size) seems like most places have it same price $180.

On the plus side the smog guy is great, walking distance from my house, used to work on 928's, proof being he recalled the joy of adjusting a dual disc clutch. Test only so he can't do any work, but good to have somebody testing that knows a bit.

First thing I think I need to do is put the car in the air and check a few things. Could be the cat is still under warranty too. I need to see what it is I had put on, but I know it was a legal Magnaflow just prior to the Calif catalog requirement.
