911 Carrera Failed smog
 

After some investigating I found out that there was no O2 sensor on my car.
There was half of an O2 sensor used as a plug with no wire leading to it!
The reason- My car is a 1983 body and electrical system and the previous owner
pulled the 3.0 liter engine and put in a 3.2 liter engine in it. There is NO wire leading
to the O2 sensor! Could anyone please tell me On a 3.0 liter 911 what color is the
wire for the O2 sensor so I have at least half a chance of finding it.
Any other additional hints would be GREATLY appreciated! By the way
The Catalytic converter is in excellent condition.
I got a 0.00 reading on the CO% at 15 mph and at 25mph
And on the (NO PPM) reading I got 1605 at 15 mph and 1330 at 25 mph
The average for the latter is 434 for 15 mph and 1330 for 25 mph.
By the way this was a California smog check.





Thanks!

I just failed CA smog on my 84 3.2. About the same Nox numbers as you .....my cat was bad and I had to replace it. Looks like you CO #'s are fine

move
we stop smog testing after 25yrs
why does california insist that old cars pass current standards the cars werent designed to meet?

$$$$$, smog reg and testing is only another scam to separate us from our money in the socialist haven. CA has a $19B budget shortfall
