Lower intake vacuum leak?

[Lx2gt]

Is there a fix for the bushings for the secondary rods on the lower intake? Mine are leaking and it throws code p1131.

that is on O2 sensor code

Lack Of Heated Oxygen Sensor Bank 1 Sensor 1 Switches – Sensor Indicates Lean

I would replace the O2 sensor as it is most likely dying.

It has vacuum leaks at the bushings for the secondarys in the lower intake. I smoked the intake and they are leaking bad. The code I basically saying the engine had adapted to the poing where the o2 sensor no longer switches and throws the fault. I had o2 sensors put on abou 10k ago

there really has only been one other documented case of vacuum leaks from the secondary rods on the lower intake.

either replace lim or dissassemble and replace o-rings.
