After doind many searches and reading TONS of posts, I decided to follow a select few's suggestion to disconnect the 02 sensor on my '80 Sc.
I immediately noticed a dramatic increase in power, smoothness and drivability of the car over a broad rpm range.

Question 1: can the lambda system be completely removed from the vehicle?
This leads to question 2: where exactly is the frequency valve and, can it also be removed from the system without having to swap out the entire CIS to an earlier unit?

I do NOT want to convert to EFI !
The CIS WILL remain !

Souk, Tsuter.......THANK YOU BOTH FOR MANY VERY INFORMING HOURS OF READING !!!!
I hope to have the chance to down a few cold ones with either of you someday !!!!
