Catalytic converter glowing red!!!

Post: #1
 
Just put a brand new catalytic converter in the truck. Took it for a test drive and when I got back the converter was glowing red. I realized that I forgot to put the oxygen sensor back in when I put it back together. could this have caused the truck to run like sh1t and the converter to glow red or do I have another problem??

edit: also do you think I might have ruined the converter??




I hurt myself today.....

Is it flowing the correct direction (On backwards???)

Thats odd, I don't think the 02 not being in would do that...

Yes, It was a whole a$$embly from the manifolds back 2 feet past the converter. no way to put it on backwards. I thought maybe with the o2 sensor out the computer might have been dumping too much fuel in and that might have cause the converter to glow

I could see the air/fuel mixture being messed up by the O2 sensor missing. That could cause the cherry red convertor. I have also seen clogged convertors do that, but with yours being new I doubt it. Unless there was trash in it before you installed it.

I had that problem. I removed the air box and it fixed it. After lookin around the air box I discovered it had a clogged inlet so I figure it was starving for air.

Check the intake system

Did a little bit of research and it seems like its the o2 sensor not being in there. Lots of places I ran across on the net say that unburned fuel causes the converter to glow red hot. with the oxygen sensor reading outside air (21 percent oxygen) the computer would be dumping fuel into the cylinders to try to burn off that extra oxygen. Ill put the o2 sensor in tomorrow and see if it helps. I doubt its anything else since Its never done it before

Was the cat clogged before you replaced it, could have some of the inards of the old one flowed back into the muffler and caused plugging?
