And of course there's probably the first thing Rawze would ask: When was the last time you did an EGR tuneup? Cleaned the system, replaced sensors.

Yeah so I had ran the rack on the engine prior to putting the motor in the truck, made sure everything was gone through. I actually have never done an EGR tune up but I did think about doing that. I was just curious on how easy is that to do? Is that something I could do or does it have to go through some special cleaning process? What about the EGR cooler? I haven't really dug too deep into the intake side too much but if this is stuff that should be done I'd just like to know if I'm able to service these parts myself. thank you guys!
