Here is the complete test (failed tests are in bold):

PASS - CO % reading was 0.05 of .57 on 25/25 and 0.02 of 0.59 on 50/15
FAILED! - NOxppm reading was 2308 of 712 allowed on 25/25 and 3308 of 786 on the 50/15 test.
PASS - RPM reading was 1375 of a 2500 max on 25/25 and 1286 of 2500 on 50/15
CO+COe% reading was 14.6 of 6.0 min on the 25/25 and 14.1 of 6.0 min on the 50/15
The Catalytic Converter was read as: Present
Fuel Cap Test 1: Fail
I'm being told I need to replace the Catalytic Converter and was wanting some advice before I jumped into that. If a converter is needed are there any good universal afterkmarket options?
Thanks in advance!

I used to live in Atlanta, GA and that emission test was a joke. My 400E failed miserablily the first test (no charge), then I just tell the guy I will be back. I drove back to the house then went back within 30 mins. The second test I passed with flying colors. Just keep testing if your car drives fine.
