Check Engine Light

Question type: Maintenance & Repair
The check engine light just came on in my car. It is sending back the code
p0430. The car will occasionally buck and stutter at speeds around 70 mph on
the highway. The stuttering will only last for about a second. Is it a catalytic
converter problem or maybe a O2 sensor? Any Advice? thanks
