Possible Lean when cold

I’m noticing a vibration at high RPM’s. Possible high RPM misfire so was wondering if anything showed in the log. Also the car threw the “29E1- DME: Mixture Control 2” so was wondering if it was related to possible running lean up top. Aside from the vibration under heavy load, everything else seems solid.

Hi Armand, Hope your Christmas weekend was good! So, I took here out just now. Could replicate the below 8.5-9.7 reading on the afr. I happens only when cruising under slight acceleration at 4500 down to about 4000. At WOT, all gears, no issues at all… Please see attached 2 different times I made it happen. Thanks, Micky.
