So I have a CEL on for code P291a, air/fuel too lean Bank 1.
The truck drives like it has a misfire, and when under hard acceleration the CEL flashes. I’ve changed plugs and had no luck. Hooked it up to Autel at the shop and it shows the same code but shows no misfire, the o2 sensors are reading correctly, same with coil packs and injectors. There is no tick, and putting it in tow/haul doesn’t make it run smoother. It’s most noticeable on inclines and and seems to have a slight rev while maintaining a consistent speed, but not enough to make the tach move.
I need help!
