EGR Toast?

[Trapper77]

I am throwing all kinds of egr codes po401 po404 po405 po06a p132B. Since I have been throwing the 405 and p132B I can not get the truck up to operating temperatures like I normally do. I am only getting up to 155 degrees on my way to work (about a 10 mile drive combined Interstate and city) Usually hit 188 4 miles into drive.

Should I get another EGR just in case this one is toast? I have cleaned it before but it never performed like this.

Would this also be cause for lack of power when towing my trailer? I could not tow it in 6th gear on flat ground because it would bog. I had to run it in 5th at about 2600. I was also getting turbo surge but ony in 6th between 11-15 lbs of boost.

Thanks

Any body

Do I have a bad thermostat? Temps here are an unusual low. High today was 34. I could not get the thing to warm up. 17 miles of driving in town and only got to 148 degrees coolant temp. Mileage is terrible to, 11.7 on the computer. Usually 15-16.

well the turbo sounds like an egr but i might also check all the boots and make sure they are all tight...that would be my guess wish i could be more help

My thermostat went out at 18K. For my daily 22 mile drive (combined highway and city, lots of accelerating and then stopping), the engine would never reach normal temps. Had the thermostat replaced and it's back to normal.
