Basket Case 04 Columbia 14.7L Runability

Truck ate a turbo bearing a few weeks back. New turbo installed by a local grease monkey.

It now has #### loads of power but stumbles and surges in gears 6+. Noticeably more when loaded.

Less noticeable when babied or driven like a #### race car. So mid rpms are the worst.

Stumble happens when rolling into the power, a quick 2-3 misfire feeling stumbles.

Surging happens when holding a steady mid rpm. Each surge accompanied with black smoke from the exhaust.

Here is what I've found so far.

#1 turbo actuator arm is not adjusted at all. Adjustment nut and jam nuts loose.

Can I adjust this close to where it should be?

#2. Air line to manifold broken. That line goes into a loom and down were it's broken again. (Red arrow)

Where should it go on the mystery end?

Did this go to a boost gauge, cause this rig dont have one.

Also in photo (green arrow) this wire not plugged into anything.

 

Could the wire not connected be for the starting fluid injector? That is no longer there for now, I've reconnected the line and on the open end capped it off. I'll find a plug.

Thanks for the info on the turbo. It's got red paint on the adjuster and jamb nuts so I dont know why the installer F'd with it.

 

One more thing. The sensor in the fuel filter housing is rotted off at the connector.

What is that sensor for?

 

Thank you qualitytruck.

Appointment made for Thursday to get it tuned.

The $6700 auction purchase is turning into a $10k truck quickly but it's not to shabby for a farm rig.
