Well the passages in the intake were clogged up, so i cleaned them out. My buddy did some testing of the vaccume system. Some of the hoses were on wrong (but i used the picture off the forum here, so apparently thats not right). Yes the Vaccume mod was bad. I had another one here that we put on. We then started getting EGR flow through the tube on the back of the engine to intake manifold. But it still didnt pass the test. Here are the new numbers
HC Max .8 Mine 1.6326 CO Max 15.0 Mine 6.3836 NOx Max 2.0 Mine 2.8283

Well, the NOx & CO #s dropped alot.
Original: HC Max .8 Mine 1.6326 CO Max 15.0 Mine 6.3836 NOx Max 2.0 Mine 2.8283 New: HC: Max 0.8, Mine .4980 CO: Max 15.0, Mine 9.3472 NOx: May 2.0, Mine 5.3327 How is the engine running? Any misfires? Hgh HC can be misfire related. Is this a 'Dyno' test?? Ours is at 15mph, then 25mph. Is it a 2 speed idle test, with no dyno? If it runs great, then you probably will need a new cat converter. If so, don't get the cheapest one out there. We call them "one pass cats". They don't last.
