What year is the van? If it's an 04 you may have a failing high pressure pump that isn't allowing enough ICP to be built, I'd be looking at this last though, rule out the other things first. Plugged MAP port, plugged EBP tube or sensor, failing VGT solenoid.
You may also have an EGR valve that is carboned up or failed internally which would explain the smoke that clears up after you back off.
