I removed the vacuum hose for the brake booster and sealed over the opening with duct tape. Same results. Running on bank 1 only. So I have chased the vacuum leaks. The only thing I can think of now is to remove the fuel injectors and send them off for cleaning and flow matching. I may be wrong about the flooding of bank 2. It may just be too lean. The plugs have a slight smell of gas, but look brand new. So maybe I have three stuck injectors? The car did sit for months. I have tried running techron through them.
