Engine Codes Help? Dp fix?

BMOEW · 07-10-2010, 01:24 PM

Got the SES light on yesterday while i was driving came up with these codes
P0420 Catalyst System Efficiency Below Threshold (Bank 1)
P0430 Catalyst System Efficiency Below Threshold (Bank 2)

I know its because of my dp's but does this mean that the fix is too weak or its too strong? I already had it adjusted before and it went away but now it came back on. Any Suggestions thanks
