What Would Cause A Catalytic Converter To Glow Bright Red


Question: What Would Cause A Catalytic Converter To Glow Bright Red,
I have a 1989 Dodge Ram Van B-250 (318 TBI engine). Last week it started ideling rough and stalling at stops. After some troubleshooting, I noticed that the EGR valve was defective. I replaced the EGR valve with a new, factory part (not aftermarket). I gave it a test drive yesterday and experenced the same rough idle and stalling. When I parked it, I noticed some louder than usual crackling under the vehicle. When I looked underneath I noticed the catalytic converter glowing bright red. What could be the cause of this?

Note: I replaced the catalytic convertor 8 monts ago

Best answer for What Would Cause A Catalytic Converter To Glow Bright Red

i wish that some of these people wouldn’t answer because they just don’t know what the hell they’re talking about. anyway, yes its your cat. converter obviously either it was faulty or absolutely if the egr was faulty and you didn’t replace it before you put in the new converter then that could have damaged it also. but now that you replaced the egr, replace the converter and you should be ok.
p.s. what the hell is a red cadillac converter!!!!
