Let me know how you make out with the test also.
Brian, I'm not familiar with the different engine names, I've got the 6.0, not a 5.3. What's the difference between that and the LQ4?

LQ4 is a low compression 6.0. You have the LQ9.

Its a long block with coils and a water pump. 2gs plus shipping. This is still a STOCK motor, by no means is it bullet proof.

I'm surprised more people aren't sugesting a blown head gasket- Am I the only person that noticed he mentioned "milky oil" coming out of the PCV?? That would explain the miss and everything else, plus a little ping on boost will almost always at least partially blow the head gasket if it's severe enough to hurt a piston.

Funny you say that, I pulled the 5.3 apart yesterday....no damaged piston and "slight" milk in the oil
Looks like I just got greedy with the boost on the ole 5.3.
