Help with major problem!!!

[mtpolarbear]

I just had my turbo off to find and fix an exhaust leak, (was coming from y-pipe to turbo), while I had the turbo off I decided to clean it. The turbo was not that dirty at all but I went ahead and cleaned it. I also did the blue spring mod and the 6.4 banjo's upgrade as well. Changed the fuel filters and an oil change as well. The problem is now the truck acts like it has a bad suspension problem with the truck shaking but I know it is coming from some where in the engine. Acts like maybe the turbo is engaging then disengaging like it shuts off completely then back on. It only does it when I get on the throttle to accelerate. If I back off the throttle its seems fine. I did not lubricate the turbo as in my research it was recommended to not do it as it could gum it up. This one has me stumped as to the problem. HELP!!!

Did you have the batteries disconnected when you were working on the truck?

Do a search on turbo re-learn. I cleaned mine a year ago used anti-seize as International suggests..............still works perfect. Tomato or Tomahto, all the same to me.

Make sure all the connectors to the sensors are firmly seated (IAT, EBP, VGT, ICP, EGR, IPR, MAP, etc)

No, they stayed connected.

Any other ideas? I did the turbo relearn and it is a little better but still sputtering.

Remove a battery cable and let sit then do the relearn again.

any chance you damaged one of the two wires going to the connector to the turbo?

do you have gauges? do you know what your fuel pressure is? you say it sounds like its shutting off and on.... do you have a boost gauge? if so is it sparatic?

Did you check the sensor connectors as suggested ................

I could have. I will check it today.

I have an Edge Insight CTS. I am saving for a fuel pressure setup for the CTS. I do have boost gauge, and it seems to be steady with good boost but I will take a drive and double check.

I am going to check that today as well. I will post the findings after I check all these items out. Thanks guys.
