Red flash light on lt8s

I just did a simplified single turbo harness. I now have a flashing red light. I dont see screen 33 where the error codes are on my dash unit. Anyone know what I should check? It does have a bit of idle hunting, trys to stall on ocassion and i did reground the ISC back to the grounds. I know I did the harness right per instructions. I have the oem harness plugged into the microtech plug an play adapter. Thanks G

Ok. Now driving around w/ the headlights on when coming to a stop the car wants to die and the headlights blackout. The car will refire and drive fine and the headlights come back on. Weird **** going on here. G

Your idle is too lean> Nothing to do with your idle screw.

My wide band is reading 11.5 to 12.0 @ idle. I am going to change the plugs to see if they are fouled. Can you decipher error codes on the dash unit? Thanks. G

Trailing will have very little to no effect on how the car runs.
I dont trust your wideband. I reckon its lean so when you switch the lights on it goes too lean.

Try richening up your idle mixture and see what it does. IF that fixes it then its simply too lean.

I see. I am getting it tuned so i get to compare wideband readings. The car drives around fine and feels good even in light boosting. Will post results early next week. G
