Rich idle
Here's my 2 cents. Your vacuum at idle looks about right at 10 or so inches Hg for the cam you have, but the AFR at that vacuum seems a little lean to me at target AFR of 16. I run about 16.4 with only 5 inches Hg. All that's really important relating to this is your plug color. If that looks good to you, then it's ok. I'm just worried that the car may overheat if left at idle too long if the plugs are too light. I had to keep tweaking the AFR target at idle until my plugs looked good. Good luck. 😀
thanks
Did you get your issue straightened out yet?
If not, one thing you may want to try is to take a look at your Fuel Learn Min in the AFR Closed Loop menu. In your log, I see a bunch of cells in a row when you're at idle where your AFR learn is -34.4, so I'm guessing that your Fuel Learn Min may be set to around that number. Maybe try bumping your Fuel Learn Min lower if it's not already (say -60.0) and see if the unit wants to take more fuel out at warm idle? Couldn't hurt anyway!
Also, is the rough idle just when warm or when cold too? I was having rough idle problems when cold, which I fixed by changing my Idle Learn Max (in Idle Control Menu) from 16.0 to 125. My Idle Learn 65F immediately climbed from a constant 16.0 (because it was bumping against the max) to the 90-100 range and my cold idle is perfect now. Your Idle Learn when warm never goes above 10, so I doubt this would help you out with your rough idle when warm issue, but just thought I'd mention it.....
Thanks. Still seems rich even though dashboard monitor shows 16:1 afr when idling. You are stating rough idle however it is rich and not rough. I will give your suggestion a try!
