That's running on two cylinders. Sounds very bad.

You folks always like videos.    I tried removing the EGR to intake boot and ran the car.  Intake sounds very loud compared to a gas engine, but I'm not sure what's normal.    Also getting a "clacking" noise out of the front timing chain area when I remove the oil fill cap.  It's got a newer timing chain assembly, that I installed during it's 2016 rebuild.    Here is the video! https://youtu.be/niglLn26CXc?si=VW53_CRqy6bfjYKV

Started digging into it now.    Engine doesn't seem to have an exhaust leak or an injector issue.  No signs of exhaust gasses being leaked, removing any injector plug causes immediate stall.   Engine has an EGR bypass circuit without a block off plate.  Pulled the EGR for inspection, because symptoms seem similar to a plugged EGR, but it looked ok.    Checked the intake manifold sensor tube for blockages as well.    Wondering if I have a fuel pressure problem, too low/high.  Don't have a diesel pressure gauge set.  I did use my gasoline fuel pressure tester and it maxed it out at >180PSI or >12BAR between the high pressure output of the pump and the rail.  Going to assemble it enough to run it normally aspirated and see what happens.    ECU is still reporting miss-fire on CYL 1 and 2.  Smokes badly, idles poorly and now very low on power. 

Thank Mike.    I've also found a CYL1 misfire code fresh in the ECU and she's smoking bad too.  Cleared to code out and took it for a drive.  Code did not return.  I'll be getting into it tomorrow for diagnostic. 

Could be a big intercooler hole. The car must be a 2006 as that's the last model year.
