I am new here, I have a 2000 Tahoe Z71 5.7 Vortec. I just installed a new exhaust system with headers and took off the EGR tube. I plugged the manifold but left everything else hooked up. Now I am getting a check engine light for EGR flow. what do i need to get onto the black box to turn off the EGR?
