Message	Both my main cats and pre-cats are bad so I gutted them. Now it smells pretty bad and I smell some fuel too. So I hook up my datascan and see the A/F base = 100 and sometimes varying between 95-110. Is this indicating something? I also use 5-gas analyzer and see when car started cold the HC value is about more than 300. After half an hour driving it would become 170-200 range. Does this mean something?
