Here are the code definitions:
P0401 Ford Exhaust Gass Recirculation Malfunction
P0151 Ford O2 Circuit Low Voltage (Bank 2, Sensor 1)
P0131 Ford O2 Circuit Low Voltage (Bank 1, Sensor 1)
P1152 Ford Lack Of HO2S21 Switches - Sensor Indicates Rich
P1151 Ford Lack Of HO2S21 Switches - Sensor Indicates Lean
P1131 Ford Lack Of HO2S11 Switches - Sensor Indicates Lean

I would take the oxygen sensors out that are before the cat and see if it runs then. Glowing cat pretty much means glogged cat. If it run with the sensors out you found your problem.

Your call, depends if you have to pass inspection or not. How long do you plan on driving car, etc. I suspect the check engine lite will stay on if you do.

From what I see there is only 1 cat for the 4.6 engine. I would get the parts and see if any hsop will install.

When you removed the 02 sensor to see if car would start where did you remove them from??? Was it after the 2 resignators before the cat?
Are you calling the 2 resignators by the exhaust maniflds cat's and the converter at the end of the pipes the resignator??? Where is the downstream (After cat) 02 sensor located? Should be on the cat at end of exhauxt pipe before the tailpipes or are there 2 sensors, 1 on each tailpipe?

i'm thinking your cat is plugged you let it get glowing red you have a big chance of catching your car on fire.

you got tuff laws there in wisconsin don't you on testing vehicles for your smog and everyting don't you? i need to replace mine in my 79 malibu but i took cat off and knocked the center out. and so far i'm getting away with it but it's a saturday and sunday car only.

1987ss, would these work?

Do you know of anybody that could weld them on? Looks like cheapest route unless you gut them.

i need to update my profile im in minnesota now and there are no emission test at this time. how much force is required to hollow out a cat? im worried about braking the 2 studs off the output of manifold... they bolt to each other(cats,manifold) . you think heating up the inside of the cat will help make it easier ? thanks

Did you remove the 02 sensor on the other side also to see if that cat is also plugged???

no i have not it is raining but i will try it. you think 2 can go at same time?

Ye they could both be bad at same time, only removing the 02 sensor will tell you.

you can also take a couple plugs out and see if it get's enough air to run if it does run like that then cat is plugged.

1987ss after reading your original post again I am thinking your fuel pump is weak. You say koeo you have 30 psi it calls for 35 to 40psi. I would hook up your fuel pressure gauge again and watch the pressure as it runs see what it does after the engine gets to operating temp if it will idle that long. The boggong down sounds like it is not getting the fuel it needs. When was the last time you changed the fuel filter??????


I would still take out the 02 sensor or try Scrappers idea.
