I recently purchased a 2006 Jeep Liberty 2.8 CRD and I am trying to determine what one of the previous owners did. I was told that an EGR delete was performed, but how do I know for sure. The throttle body is just zip tied to some wires. What parts are needed to install the throttle body? I need to get this vehicle inspected, but the cel is on and need to get the Jeep to a point where it would pass inspection. Can I just remove the throttle body from the Jeep? It is still plugged in. Will this throw a new code?
