i have a 2000 Integra 5 speed, and its giving me this problem...it doesnt do it all the time, but it does do it frequently to discomfort me, it does it when im accelerating, and it suddenly bogs down, or it hesitates to flow...if anyone can help please..i also have an idle problem, not severe, but evident...



Codes it's giving me:

P0172-system too rich bank 1
P0420-Catalyst System Efficiency below threshold
P1457-System leak detected
