Engine Bogging - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a problem with bogging from idle to about 2000 rpms. The bog is still there above 2000, just a whole lot less noticeable. It doesn't start happening until the truck is warmed up. Once warmed up, the problem comes and goes.
This is on a 350TBI/ 700R4. I have completely gone thru the TBI/Fuel system and had a computer hooked to it. Everything in the TBI system is working as it should, and reading on the computer as it should.

So, this leads me out of the TBI system to look for the problem, which is where you guys come in. What could cause an intermittent bogging issue on a warm engine?
