O2 Sensor ??
 

I have had my O2 sensor disconnected for the past couple of months because of stalling and just got my registration today requiring a smog certification, can I pass smog without the O2 sensor. I really don't know what role this plays in the whole emissions system.

Hey Chris, you might pass but it's very doubtful. When you unplug the O2 sensor your car runs rich. Plus without that sensor you lose some mpgs.

Just plug it in for the test or come up to Glendale, I have a friend of a friend that will pass yeah :D

Draco,
Can I ask his name, address, #, and lisence #? :)
