Question Is This EGR??

Alright guys, here is the deal. I have been running my truck with the EGR unplugged for alittle while now because i felt like my EGR was failing and just decided to try it. Well it has been using more and more coolant lately so i decided to use this warm day to go and work on it and check some stuff out. Well i plugged the EGR back in today and there are alot of things it is doing differently..

First off, my EGT's are alot higher and get there alot faster. With it unplugged it would only get around 900 if i was on it pretty good. Plugged in it gets there easily. It also blows plenty of black smoke plugged in and NONE unplugged.

Secondly, the ECT with it unplugged would stay around 178 which is very low i know. After reading on here i thought maybe my thermostat had gone bad. But, with it plugged in its alot more variable and stay up around 200 where it shud be. I was getting horrible gas mileage with it unplugged and was thinking it was because of the ECT not getting to normal driving temperatures.

My question is, would the EGR cooler going bad cause all of this?

I was planning on getting a delete this week and i was also wondering if, when i do, is my mileage gonna go back down to horrible like this?

Mods are in my signature

Sorry for the long post and TIA for any help.

Go see Scott over at Trucks Unlimited in Winston - Salem..... Him and his boys just fixed me up real good.... Same problem

Sounds like your EGR ate it, killed your EGR cooler, and I would bet killed your oil cooler as well..... AND if you are drinking that much coolant I would say there is even a good possibility of head gaskets..... Scott is a straight shooter and will save you the most money..... IMHO

If you're using up coolant, it may be your egr cooler. I just replaced my egr and oil cooler. Mine was using up coolant. When I removed my EGR, the soot was all goopy. I was also blowing out white smoke/steam from the tailpipe. Anyway, it's all fixed now as of yesterday.
