I just had my 1985 500SEC tested, (it's a Georgia thing) and all test parameters were excellent (or even better) except for NOx which was 3900 with an allowed 975. There is no EGR on this car to fail, so what do I do now. The car runs great, gets good milage, HELP. Any suggestions or recommendations.
