I'm having a strange issue with a 2000 A4 LS1 Formula. My whole right bank is misfiring and I am also getting a lean code, when I add carb cleaner into the throttle body, the idle improves for a second then starts misfiring again....I ruled out the coil packs.

Also, I know that the fuel pressure during KOEO is 55-60psi, does anyone know the fuel pressure during idle? Thanks in advance!
