You do know what that does right? I guess not if you mentioned it. MIL elim. are not a fix for this code. I'm guessing a bad EGR or DPFE. Tube under the TB might be carboned as well.
Todras,
Actually, MIL Eliminators will help with the P0420/P0430. After all that's what they're for!
The P0420 and P0430 codes are generated when the downstream sensors switch too fast, that is, too close to the switching rate of the upstream sensors.
The purpose of the RC integrator circuit that is the MIL Eliminator is to slow this switch rate down so that the computer sees a longer term average reading with considerable lag - just like a normal downstream sensor would produce if the converter was working at reasonable efficiency.
