Ya, tune out the rich condition, and monitor knock.
False knock? Motor/trans mounts, body hitting dp, loose converter bolts, cracked flex plate, defective knock sensor, etc, can all be contributing to the issue.
Post up some data logs.
This is on your TR, and not your Yugo, right?? Posting the combo may help.
