I’ve seen the afr bounce all the way from 13.6 to 15.2 that’s just off of memory so I might be a little wrong on this numbers. But I know for sure I’ve seen it hit 13 something and seen it hit 15 something at idle.
At first I thought I could be because they are UEL headers.
I tried to make sure the O2 sensors were tight the other night. Couldn’t tighten them up or loosen them any with my normal wrench. I ordered a tool right after that. Going to try to inspect them maybe I need a new one or new gaskets. I didn’t even know it had a gasket, but I didn’t put them in my friend did and I tightened them.
