During part throttle my wideband suddendly reads lean and the car begins to bog. It runs really lean, like 17-19. The car does this after driving for a few minutes. I give it more gas or I rev my car to about 5000 or 6000rpms and the problem is gone. A friend said to disable the o2 heater. This worked, but the problem still happens every once in a while. Closed loop is not disabled right now.

 

try disabling closed loop in boost
