Attempting to destroy my idle lumpiness

I think that would be irrelevant as the ecu would only go open loop when the lambda switch would go open circuit once the coolant water temperate goes above 80c.

My car goes closed loop in about 15 seconds from a cold start. I don't have the WOT/temp sensor wire hooked up to the lambda ECU. I have a "power" switch that sets 13 AFR if I want to get more power. But I really never use that power setting.

That makes sense if you've got those disconnected.

Anyone lately do NickT's suggestion on fix the hunting idle?

I just read this thread and I'm filing it away for later. I'm almost done with a frame-off restoration and it seems like my idle is a bit more erratic than it was before I started. I am going to have to check all the switches and sensors to make sure they are working, and if they are, I might try something like this. Won't attempt it until I've confirmed everything else though with a smoke machine, timing light, and fuel pressure gauge though.
