Unhappy 2003 7.3 flooding

I have a 2003 7.3 power stroke that if you leave the inter cooler hoses hooked up and try to rev it up, it bogs down and boils out black smoke. Un-hook the hose and it runs fine. Revs up and no smoke. I am guessing:lack of air, but WHY? Waste gate stuck? What controls the waste gate?

Did they let a rag get sucked into the IC ?

It might be a stupid suggestion, and I'm sure you already checked it. But when was the last time you changed your air filter?

Something has to be stuck in the intake somewhere, blocking the air flow.

In that case I have to agree with the rest of the guys here. If the turbo spins freely and the air filter is clean, then there has got to be something stuck in there somewhere.

If I had to guess, I would think Rick probably has the right answer with the rag.

What made you decide to pull the IC tube to see if it would run better? That sounds like it had to be a last ditch effort, or a very lucky guess. Either way, welcome to FTE Ted.

It was a last ditch idea. We didn't get the manifold off yesterday, maybe today.
