944 didn't pass smog.. seeking shop in Los Angeles

[Andrew]

I am told that it likely needs a new o2 sensor. Looking for a recommendation for a shop in Los Angeles or Pasadena that knows what they are doing. Thank you for any referrals.

The O2 sensor is a piece of cake to replace.

* Order a generic O2 sensor for your model year. Mine is an '84 and I think I paid about $35.

* Run the engine for just a few minutes to warm the pipe a bit.

* Remove old sensor, cut wire, crimp wire for new sensor on to harness end of wire. (If you have a three wire sensor you of course have to connect the additional two wires as well.

* Install new sensor.

Hydraulic clutch went out in Mexicali. Think it needs rebuild or replace master/slave cylinders. I will get the car back into the US this week and will likely find a way to get it to San Diego. Anyone have that reference for a 944 mechanic but now in San Diego? LOL, but that would be the most convenient. By the way, I live in San Felipe, Baja, so that is why this is such a challenge.

AFA the smog, here are the numbers. The car passed visual, failed emissions....

I think I read on another board that excessive NOx is likely due to the Cat Converter going bad.
