Mein Auto: 1996 328is
1996 328is CA smog check fail

Daughter's 328is just failed the much hated California smog check. The numbers are as follows:

HC (PPM) NO (PPM)
MAX AVE MEAS MAX AVE MEAS
15 mph 54 9 78 430 67 446
25 mph 37 6 37 717 62 192

Basically failed at 15 mph for HC and NO. Going to start by changing out O2 sensors and plugs. Just changed oil a week ago. No CEL codes. Any other suggestions?
