1998 I30. first owner. got P0400 at 195533 miles

[infii30owner]

what could be going on? i hooked up the autozone OBD2 reader and it showed like this:

1 code
P0400
MIL on
Monitors
Evap
EGR
Misfire
O2 sensor
R2 sensor
Catalyst
(2 others)

i'm the first owner of this i30. had 195533 when SES light came on.

appreciate any guidance. mechanics say engine is still good.

I had new NGKs 2 years ago. all 6 ignition coils are from same set.

thanks.
