Can disabling the air pump kill main catalytic converter?
Hey guys here is my story. A fellow forum member came up with a brilliant idea to have the fans run full blast to keep the engine cool by just pulling the AC fuse. So when you turn on the AC button from inside the car this keeps the fans running full blast. The only problem i noticed was for some reason by removing the AC fuse, my air pump stopped turning. Now i had a catalytic converter that came with my car when i bought it and i had it inspected and was told that it was almost toast. I put it back on because i was getting boost spikes with my Midpipe and was running my stock Ecu. So I have been running this Cat for quite some time now and have noticed that half of it has gone black, looks like oil caked on it, which tells me that it is toast. Now i have just purchased another Main Cat with only 20,000k on it. Now i want to know is if the airpump isnt turning well that kill the main cat?

Yup, w/o fresh air the new(er) cat will burn up just as the last one did.

Excessive fuel is bad for cats, and this is more likely your problem. Know what your AFR is?

While trying to figure out an airpump solution for my single turbo, a tech at Random Tech explained that barring excessive fuel, a cat should lead a normal life w/o an airpump.
People that remove airpumps typically do so when modifying their cars, and a cat gone bad is more likely due to a less then perfect state of tune. That, or cats in most rotaries (before the Renesis) are just doomed to a short existance, due to the neccessarily rich state of tune at idle/low rpms.

So, dclin, what you're saying is, those of us that still have cats can rid ourselves of the obnoxiously loud airpump, and not shorten the life of out cat? (please say yes! )
