What makes the catalytic converter go bad?

Many of the compounds that make your engine oil work better on the INSIDE of the engine are also "poisonous" to your catalytic converter as your engine starts to use oil. The nice thing about catalytic converters, they burn unused hydrocarbons that come out the exhaust. You may not KNOW that your engine is burning oil until the catalytic converter gives out or even gets plugged up. Watch the oil level in the crankcase. If it drops with no evidence of leaking, it's burning and your catalytic converter will die.

How do you know when you need to replace your catalytic converter?

A catalytic converter could need replacing for a couple of reasons. If your municipality require emissions testing a defective converter could be the source of fail emissions problem but the most common reason that a converter is replace is plugging off the exhaust system lowering the performance of the engine. If your car appears to run properly but lacks power a clogged catalytic converter could be the source of the problem. One of the quickest ways to verify this is an intake manifold vacuum check. If the vacuum reading is low and steady this is an indication of a plugged converter.

What would make the catalytic converter on a 1995 GMC Sonoma glow red?

your catalytic converter is plugged up most likely. Are you experiencing low power output or a "bogged down" state when you accelerate and drive? These too are all symptoms of a plugged catalytic converter. An easy fix if you or someone you know has the tools, is to simply torch or cut the converter off the pipe, use a rod and hammer and hammer out all the guts. Then weld it back on place, preferrably with a MIG welder, but a stick welder would work too..just not as nice. Do it this way, and you save yourself almost at the least, $200 in repairs from a mechanic.
