Well, after my problems with passing emissions, I've learned something new. Some may know this already, but this is for those that don't. My EGR wasn't working and causing my NOx to be VERY high. WI limits are 2.00 g/mi (not sure...grams per million units?) and mine were 3.00 and 3.16 the first two tests. I tested the EGR per the Haynes manual. There was 19 inches of vacuum going to the solenoid. 5 inches to cause the car to stall out at idle. Proper voltage. The one thing not tested was the vacuum between the solenoid and the valve. I put a "T" fitting and vacuum gauge between these two and took it for a drive. When cold, at idle, and WOT the EGR should be closed, no vacuum. At "normal" acceleration and constant speeds, the vacuum should be between 3-4 inches. Mine stayed at zero the whole time. I swapped the solenoid with the one on my Sebring and it worked.

I'll get some pictures up after I get home, I just got back from the test station and PASSED it! WooHoo!

Later...Andrew
