I have my older logs, before vette tables. There is no knock at about 4000. I'll try to make more cruising logs.
Also I dont like maf readings. 6-7 at idle. I'll try to clean, but I'm afraid he is dying.
No vac leaks. Checked
O2s readings vary to much (left/right)
Rarely I get right or left (dont remember)bank lean condition dtc.
