Never got a CEL for mine, and sorry to say I didn't get the heavy metal version. I got the 94009 unit.

Had the cat for almost two years now, no problems, although I stopped using ethanol gas completely shortly after I put it on. Only run it once in a great, great while when I have to... which is visiting the in-laws in Minnesota, as its state law there that all octanes must run 10%-20% ethanol.

 

hey for everyone i dunno if it was just my sit or a general thing but i was getting the same code when i first purchesed my 98 dakota upon inspecting the cat i seen it had been cut open and im assuming gutted all i changed is the cat and my muffler i did NOT change either sensor and no code since no problems either hope this helps at all
