I think I narrowed this down. I listed this in a post I made titled "several minor issues" but, this is more specific

when I start the engine cold, MOST the time (90%) I get no check engine / 43 code. (only code it throws.

however, when I stop (like go into a store, fuel up, etc. .) I almost always get the code 43 (start with warm engine)

I won't know till warmer weather if the code is more frequent yet, but, this is what I'm getting now in cool weather

I don't have a digital spedo, rolling analog digits, I have to get codes by counting check engine light flashes.

any ideas what could cause the code based on this more specific info?
maybe what sensor could be bad or need cleaning?

thx
