I got this from wikianswers; There are (4) O2 sensors on your truck. If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath the truck about half way back in relation to the transmission. If you see where the exhaust joints together, you went about 6" too far. When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat). Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions. You will need; Oxygen Sensor Socket Anti- Seized Penetrating Oil Sometimes it will take 15 minutes or take a few hours it depends on your luck. Hope this helps

I admit, I didn't even consider a vacuum line as I made the mistake that they had already been eliminated. Glad you found the real problem. Sorry for all the $$$ spent learning.
