1996 2.3 Five speed. Sputters and will stall when stopped, worse when it is warmed up. In neutral, I can floor it and it bogs, if I ease into the gas it seems fine. Runs fine on the freeway will sputter on the streets. It always sputters and stalls when turning left, but not turning right. Has a code. Forgot the number, it is a lean code in bank one. Any ideas?
