> Thanks for all the helpful replies and advice, but I just have a quick question: Is it bad for the car mechanically if I don’t get the problem fixed, or is it just more of an evironmental issue? If it actually decreases the performance of my car, I should probably just get it done right and do a re-test. Any opinions??

I agree your timing might be off causing excessive hc and nox but that would be in the low hundreds not thousands… your egr is likely malfunctioning, which can lead to mild pre-ignition at light throttle or at the least retarded timing… which makes even more nox and makes your cruising fuel economy garbage
