So an update on what's going on. I took the car in, turns out that the two forward cats were disintegrating, and clogging the back one with chunks. The mechanic took out the back cat, cleaned it out, and it was o.k. he also broke loos the guts of the two forward cats. The car is still doing the same thing (won't rev above 2300 rpm or so, it will get up there, and then kick back down below 2000). He's working on trying to figure out whats wrong. do any of you have any ideas? He said his tech's first guess is timing belt - but that was just replaced a little while ago (probably close to a year or maybe even longer).

thanks for the tips - sounds like too big of a job for my meager tool box though. I'll call up a muffler shop and see how much they will extort for replacement.

I have a 92 sc400 with ~ 100k on it. One of the cats just decided to fail, and I'm wondering if it is safe to gut it, and run like that until I have the cash to buy new ones. I've heard that there are overheating issues with gutting them in some cars. I don't want to cause more problems. Also, does anyone here have any experience with this? I'm not sure of the exact location of the catalytic converters - do I need to get the whole car up in the air, or are they in a position that I can access more easily? Thanks for your help, Daniel
