O2 question

Hello,
The Tbird was running great then started an off idle issue. When I stabbed the throttle from idle the motor would bog down pop and dye.
Found out O2 sensor harness came loose melted to long tube headers. Replaced both O2 sensors and extended harness, Reset KARMF I think, (went into BE swithed KARMF to reset hit update then back to normal hit update) Ive noticed now if feather in the throttle fast I can get by the bog pop dye but before the O2 harness melted I could go from idle to WOT no issues. Anyways Ill attach the Log. Does the clear KARMF procedure sound correct.
THanks
Nate

Yes I agree something is amiss. I looked over data log a few times I notice it not getting any spark advance coming off idle. Trying to figure out why not now

Asking for help again,....Data logged the event and Iam seeing weirdness, if I read it correctly. Looks like , Close loop flags to 1 and the timing does not advance. If I come off throttle fast enough letting it return to idle or restart it all is good takes off like a rocket. I replaced coil pack and plugs before data log with no change. I still think its mechanical or sensor seeing how the tune has not changed since I didn't have this problem. If anyone takes a look and sees something or has had a similar issue Ild be glad for info. Maybe beer money if help fixing it wink wink
