The quality thing is because that site is showing the image smaller (and in less quality) so it fits on the screen better. Just click the image and it will go to its full size and quality.

I think the KE-Jetronic is the system used on cars with a catalyst and 02/lambda sensor! I think the 2.5-16 without catalyst is K-jetronic? Does the book feature that too?

What the hell is that? It sounds identical to the idle speed air valve to me??!!

I thought it did? In which case, why does it also have a sensor going to a computer as well (read in PART 6).
