If you want to do a quick check yourself, the 2000 Neon is easy to do.If the converter is clogged, it would set a code because it has an O2 sensor before and after the converter.
I would suspect clogged injectors.

I would volunteer to read out the codes with my OBD scan tool but it's buried under 85 ft of lava in Kapoho.
