Not needed, a recall removed these. It's a pcv shutoff. Get rid of it

the Nutter bypass is named for Nutter, someone who first came up with the idea. Essentially you modify your ignition wiring to take the fuel control for the electric stepper motor away from your carb and the ingition control away from your computer, so that you no longer have a closed loop emission controls system run by the ecm. Once you 'nutter' the vehicle, the ECM and everything connected to it no longer has any control of the vehicle ignition or fuel and can be removed if you choose. You can take out the pulse air tubes, the pressure solenoids and most of the vacum lines and junk running around the engine bay. Look at the links posted, or in the Frequently Asked Questions stickys at the top to get a full description and how to.

Before doing the nutter you need to worry about the inspection. PA is a PIA! Please read and check before doing it. The nutter and team rush will make your Jeep run infinitely better BUT:
