No prob. The Carreras are a little different than our SCs in the fuel injection department.

PASSED!!!!
 
Yes!!!! I finally passed with flying colors...sort of, but I passed.

It was the oxygen sensor I'm sure. (my wrench forgot to hook it back up last year.) But running 87 octane and techron the last couple days probably helped as well. Thanks Mikez, Wayne and all of you who suggested I was running too rich.

I did not do the injector trick cuz when I test drove it last night like that it idled way too rough, so I went like this.
Look at the the diff - before and after:

So I am now legal, even though she doesn't run quite a smoothly as when she was rich. I'll start working on that.
Thanks!

Seems you have a different test in your county than we have here. Yesterday when I had my car smogged, they ran it on a chassis dyno at 15mph and 25 mph for 90 seconds each, in second gear. I know the state varies on testing levels by county. I'm in El Dorado county (includes Lake Tahoe) and that is the requirement here. I also noticed the max levels on my sheet are different than yours.

The max levels are different for different year cars. They get stricter for newer cars.

I hate to rain on your parade after you passed, but running the car for a year that rich might have damaged your catalytic convertor, and sometimes damages the O2 sensor.
Since it passed that idicates that neither is in real bad shape and since it ran good before that cat is prolly not plugged but the O2 sensor could possibly have something to do with the rough running.

An OVA meter (measures HC) will not pick up oil unless it is designed to do so. One calibrated for a gasoline engine will not register the oil as unburned HC.

Yup. I fear that too. I'll swap out the O2 sensor and see how she runs.

Ya, we have no dyno test here (about an hour north of Santa Barbara.) But they do where I'm moving to.

I should rent out my current address to my L.A. friends.
