A new evil bug has appeared so I'm replacing the heads and VVEL ladders. I'm starting with fresh mechanical items from a known working car.
Currently with the VVEL all good as far as the sensors say. The car will start up with Bank 1 pegged lean and Bank 2 in the 12s AFR wise. If i give it a little throttle and let off slowly it will clear up, fuel trims and AFR's will be normal until something (no clue what) causes it to go back to ****.
