Catconverter burn-up..
#3
lets start over, who said the burned up 2 Catconverters now. by what measure, P0421 codes, or smog man or?

The P0400 means the EGR fails.....  in some way , if the cat GUTS broke up in pieces and went byebye EGR then fails too.  the cat must be there and must have normal back pressure or the EGR Modulator FAILs to work. (goes offline) and P0400 is the results. but is the effect not the cause, in this case. (or there are 2 problems, unrelated, and common on old cars)

did you fail a smog test or something, please advice  here.
thanks for posting !
