no fuel off idle 200 1979

Hi Mike,

This thread, so far, has excellent replies. Not much I can add, except to reinforce (from experience) the notion a cheap AFR may not work well for diagnostics for the reasons 81 gives.

I think I may have the same setup you do -- 79 non-lambda EGR. More from curiosity than a symptom like yours, I added a narrowband sensor for a test and with it discovered that without a feedback system it really works much like a light switch with the normally wide mixture variations a k-jet yields under actual driving loads. The conclusion I came to was a wideband meter was needed for what I wanted to see.

Here are a couple visuals from my 79, and one jar-squirting video on the bench that is not mine.

I'm curious how this all came about for you, or whether you got the car with this behavior.
