My 95 S320 has been slowly loosing power, but hasn't been throwing codes or having the CEL come on. I"m wondering if my cats aren't plugging up. I was thinking about removing the exhaust to see if they are plugged. If they are plugged, I was thinking about simply cutting open the cats and removing the honeycomb. There's no emissions tests in my province, and I feel no love for the EPA types, etc.
My question is, if I remove the honeycomb, is there a consequence for any sensors in the exhaust stream?? Will I be getting codes thrown up on a constant basis?? If there is a sensor in the system that would be effected, is there a way to override it??
Does anyone have experience with a car of a similar age??
I have not looked under the car to see if there is a post cat sensor either... I might do that in the morning...
Thanks in advance...
