re: OT Mechanics - Are my CATS clogged?

it sounds like a clogged Cat, but the clogging could be caused by another issue. You can always remove the O2 sensor and tell pretty quickly
It was running shitty for a while so I re-did the ignition system which cured the issue. Figure maybe it killed the cats dumping fuel in them leaving me with this issue??
So I can remove the O2 sensors to bypass the cats? That sounds like solid advice rather than removing the cats themselves

Who the frick let's a 92 model idle for 30 mins with the air on? Surprised it didn't quit altogether.
By that you mean.. lasted 25 freaking years and 400k before it was an issue?? I do this every day on lunch during the summer. If its not a complete piece of shite that overheats I fail to see the issue. Letting it idle didnt kill the cats

it wont by pass the CATS, but if you see an improvement in engine sound and performance, it will lead you in the right direction. The O2 sensors help to burn off excess fuel before reaching the CATS if your fuel mixture is too rich and to keep them from clogging. It could be an issue with the O2 sensors and not the CATS, but you can use it to diagnose the issue.
