Crap! No! any suspects?well going to have to see what happened. Have bigger fish to fry now, I'm down compression on one cylinder. Oil test leads me to believe it's the rings.
In my case, I was finally able to make the Target AF work, and is working ok, 12 steady AFR across the powerband at full load, should work ok as a good correction factor for weather changes, crappy gas or stupid gas + 10% ethanol.
Now onto another thing, and this has been happening even when I did not have the target afr setup (so isn't that): Everytime my car reaches operating temp, and lets say I go do some errands and turn it off, sits there for about half and hour and I come back, when I turn it back on, it goes to fully lean 16-17 and even no readings on my gauge, hesitates a bit (i can hear it hop hop hop), the cure is to give it a few revs or start driving, and after like 30 secs or more it goes back to normal idling at 14.7.
It only happens like I said, when I let the car sit sometime and I turn it back on with the engine still warm, and only for the the first 30 seconds or minute.
