Changed out my exhaust to a Flo-Pro 4" downpipe back, Installed the H&S Mini Maxx, and installed the H&S block plates, and the AFE intake. Tomorrow I will be doing the rest of the EGR delete. I started up my truck and went through the screens of the programmer. Now i have a CEL. I unplugged both EGR plugs and installed the EGR Block Plates. I removed one of the EGR probes from the exhuast and installed it in the EGR block plate and the plug that into where the one was in the EGR Tube (the small tube that was removed). Does anyone know what might be causing this CEL???
