ISX flutters at idle

I have no trouble start ing it.

 

Put truck in the shop last week and they finally got to workin on it this week, but that's another story... anyway... They're telling me that everything tests good and the actuator moves freely but the VGT codes indicate replacing the actuator control. Any input???

 

Now they install new actuator and say so sorry the actuator ring is sticking and is really not opening all the way - you need a new turbo. Price - about $5,000 parts and labor. I ask will this solve my problems - surging at idle and poor fuel mileage? We don't know...

 

Kenworth. They were the only shop that said they could Get on it the next day. They finally did 7 days later. Turbo is $3100, actuator $900, labor $700 plus taxes. There is a brand new turbo with actuator on EBay for $2500 including shipping. Thinking of paying labor and pulling truck out of shop, buying EBay turbo and installing. Will save a grand but lose 2 -3 extra days. My biggest obstacle is getting willing to throw more money into this pit never to be seen again and still have the same problem when I'm finished. I feel like Wyley Coyote trying to kill the Roadrunner...

 

I've owned this truck for a year and it's never been right. I'm running Rawze's tune. My local Cummins dealer (Orlando) reminds me of the three stooges.
