Just finished an EGR delete oil cooler replacement.

2004 6.OL diesel Excursion.

Car started after long cranking. More exhaust smoke than previously.

Seemed to run fine. Took it for a drive. When I really stepped on the gas the engine died and I pulled over. Started up again just fine.

I did notice this vaccum type device on the passenger side which now runs as soon as I turn on the key.

There was a vaccum line that went into the top of the intake manifold passenger side. The end of it was slightly cracked when I reinstalled it.

Could the two be related.

Short video here of the problem.

How long have you ran it? Just asking because maybe there is some air in the fuel yet.

That sounds like the line that runs to the MAP sensor. it must be plugged in.
