ok, last question...i saw this on ny-jbodies and i was wondering if someone can explan it a bit more.....

We removed the egr and mounting bracket from the head, kept the egr plugged into the wire harness, and ran a vacuum line from the intake manifold (any port but FROM THE MAP SENSOR) to the large open port on the egr. We used a brass nipple fitting and a filtered air line fitting (3/8 pipe thread), and tapped the large egr port with a 3/8 NPT tap. No check engine light. Then just zip tie the egr out of harms way.

being your car is a 96, you have 2 options........ one, leave the EGR off, and live with the EGR CEL......... or try and do that mod you pasted above. I originally did that mod on the first car I put the HO manifold on, and it seemed to work fine...... The trick is to make the MAP sensor see a change in intake manifold pressure, when the EGR opens, other wise it sets a CEL for 'Low EGR Flow'...... thats what your doing w. that mod. It has the EGR plumbed into the intake, and when the PCM commands the EGR to open, the MAP sensor sees a change in vaccum, and everything is happy.
The only problem, is that your letting in fresh, oxygen rich air. Normaly it would be letting in exhaust....... which has a lower oxygen content. It might take some playing, to get the right amount of air flow, threw the EGR, to get it to work correctly.
There is a 3rd option, but I dont think anyone actually has it working right. That is to install a EGR sim, but because its ment for a larger engine, its not calibrated for our motor.
