I started my truck and check engine light came on, drove into town and had no power and didn't hear the turbo whine. It ran fine the day before, only got 68,000 miles, could turbo have gone out all ready? I installed my ez but didn't put in the elbow in turbo, hated to cut the braided line. taking in to cummins to have checked out, if turbo is bad looking for suggestions on replacement.
Thanks you guys have been great with my other problems!

 

I like to look at the bright side of things til I know otherwise...it could simply be a code was thrown on your truck and put the auto tranny in limp mode.

It may just clear itself after a few starts/stops...I think three or five was the magic number. Try it.
