It's glowing red hot again after I cchagened it I don't know what the problem is I'm scared to drive it because I will have to buy another catalytic converter so I don't know what to do
When a CAT runs that hot it means the engine is running too rich. You can cause a fire. Make sure that all the cylinders are firing
How would I check that and fix it.
There are a lot of things that could be causing this. If it is fuel injected, you may have a bad or plugged injector. You may have a bad plug or wire and that cylinder is not firing. You may have a bad MAF sensor or air filter. When was the last time that it was tuned up? How many miles are on it? What is the year, make and model
It's a 1992 honda civic about 225000 miles I already changed the air filter, spark plugs, spark plug wires, fuel filter, put a whole new muffler system, and It has been awhile since anything has been done that's why I'm doin all now because the last owner didn't do anything to it. I'm confused?!?
And it's a carb orator
I would say a couple of things about this. If you use gasoline that has alcohol added, it can cause the float to sink or become heavy. This would cause the fuel to be excessive.In any case the only sure way to tell is to have an exhuast gas analyzer put on it. The other thing that you can do is get a rebuilt carb. Try autozone
I think I may need to clean and or replace my map sensor
Check the hoses that connect to it. A leak in the vacuum line can cause the MAP sensor to do this. Those sensors are not cheap either.

SOURCE: New catalytic converter gets red hot
clogged , check the rest of your exhaust after cat to see if it gets hot
you can buy a no contact thermometer for less than $55.00
but the shop that installed the cat should have that
good luck
SOURCE: my exhaust pipes are glowing hot
The catalytic convertors are no good.They are severely restricting flow.Do not drive until repaired.The car could burn,or damage to the engine could result.
SOURCE: My catalytic converter gets red hot after 5 min of driving
yes this could be the fault but you would have a light on the dash in the shape of an engine this is the eml light>engine managment light)this is the computer he is talking about unfortunatley yes it could be costlyit has a lot of miles on it hope this helps you
SOURCE: red hot catalytic converter, motor shaking, and no codes.
well you could have had a cat converter go bad before thats possible,either you now have a piece of the old broken cat stuck in the exhuast pipe,or you have what i think is a bad ignition module/coil pack and spark plugs causing a major misfire causing it to over heat and have no power,,,or its out of timing causing the same issue,,its odd it has no codes,no ses light,if its a bad coil its got a ses,,these are just a few ideas its too hard to tell without seeing the car

Hi ,
First you need to stop driving the car !,the problem you have is massive over fuelling causing the Cats to super heat this can cause a fire risk under the car,you need to take the car to a qualified mechanic/garage ASAP,You have probably damaged the Cats already but if you keep driving they will melt and colapse internally and block the exhaust gasses causing lack of performance and even non-start.
