Engine management

So I had a problem with car, it was running lean, so I replaced both 02 sensors, car is running far better,

BUUUT, whenever the car isn't on choke, or moving forward the light comes on, when I'm idling, reversing at running temperature the light comes on, I believe there might be a fueling issue, I've noticed when idling at running temperature, just before the light comes on, it sounds like it's gasping, any ideas and possibly the location of the fuel rail before I start ripping stuff off
