Hi all,

How can you tell if your cat is getting clogged? Would an O2 sensor error
be an indication? I know the O2 sensors can go bad, but isn't that what
it's suppose to do is give an error when cat is clogged?

Thanks !

Hi Kevin,
I clogged my catalytic convert using leaded gasoline, on a day I
normally accelerated from a dead stop out of a residential zone up a
hill past a sign marked 55 MPH, I noticed I was only doing 45, when
normally I exceeded the speed limit at that point. Also you'll hear a
jet like sound coming from exhaust pipe at full throttle. I would say an
Oxygen sensor error would be the sensor it's self, or it's connection,
rather than recording a condition.

OK, since the dumb jokes are already covered.....

Yes, a rear O2 sensor code could indicate a problem with the cat convertor.
More likely though, at least in my experience, it's just a bad sensor.
After making sure there were no wiring problems between the sensor connector
and the computer, I'd replace the sensor, clear the code, and drive for a
while and see if that fixes it. Unless, of course, you have other factors
that indicate a bad cat, and you just didn't mention them in your original
post......

Bad, bad, bad Jim!

Gawd! =)

Your clock on your computer is messed up eh...

No, not in my CJ, I think I was in the Cherokee and we were running
every Saturday and Monday on the 401 from TO to Belleville then north
Bon Echo Park way every weekend in May up to the first one in June.

I saw a Jeep that looked like yours somewhere close to Toronto, Yonge
St. area north of the 401 I think, maybe not you.

Pretty much what I went through Bill. Just recently put a new high flow
system in and wowsa... an incredible difference in acceleration and mileage.
I didn't need a sensor to tell me something was up!

Burn or drill a small (1/16") hole in the exhaust piping before and after the
cat and feel the difference in pressures. Plug the holes afterwards. A muffler
shop can do this rather quickly.

They usually unplug themselves by pushing out a hairball. Sometimes the clog
at the other end, but a diet change to wet food will usually fix this.
