Hey guys

i need your brains once again -- my 90 na z 2+2 zx has had hesitation problems most of the year - bad o2's - fixed bad o2's again -- the question i have concerns the cats -- i read somewhere that bad o2 sensors can destroy your cats & clog them ?? is this true ?? i am replacing them with test pipes next week -- but i still seems like the power is down comparing it to my previous 90 NA z ??

your air fuel is too rich that's why your cats are bad and also why your eating up 02 sensors like crazy

also if your car has ever had a misfire for a period of time, that will ruin your cats as well. my s13 is proof
