new guy from santa barbara

[81 yota]

Got an 81 yota and have been working tirelessly to get it to pass smog. Swapped engine etc

Did you replace the cat?

[81 yota]

Yes sir cat various valves. tomorrow is the moment of truth

[81 yota]

So does the 81 need an o2 sensor? I bought one, however for the life of me I can't find where to plug it.

Welcome ... all the best ...

[81 yota]

It didn't pass the guy said it needs an o2 sensor and he said the egr valve is constant when it shouldn't be. I'm gong to switch out the egr valve from my spare and just connect the o2 to a random wire to see if it will pass.

welcome.
