4.0 Cats Glowing

[Briebennett17]

Hi , I have a 1995 ranger 4.0
Can I remove the cats and stright pipe to the muffler ? I was just sitting on the side of the road as the cats have clogged up and the only way to check the truck from stalling was to remove the 02 plugs .
Not looking for long term just a temporary fix .

No. The act is illegal, a federal felony, so don't give any excuses about "But my area doesn't do emissions testing". Removal of the cats makes the vehicle illegal to operate on any road maintained with any federal funds.

Also, the discussion of such illegal activity is against forum rules.

Lastly, your 95 is OBDII, so it has cat monitor sensors, and you will get a check engine light.

And there's nothing to gain performance wise if that's your goal here. (It'll actually hurt performance). Illegal and pointless.

I wasn't aware of that . I apologize .
I just recently spent two hours on the side of the road with the truck not even able to keep running . When I inspected it I found to glowing red cats .
I was able to pull the o2s to get home . Was just wondering what I could do till I could get a proper fix

No I was just broke down on the side of the road and had to pull the 02s to even be able to limp it to the house . I was wondering if it was possible as a quick fix till I could send it to the shop .

What are the codes? Cat's are probably fried but could also be red hot from excess fuel. Would be impossible for them to get that bad with no DTCs. If you don't fix the problem you will just ruin new cats if you replace them.

That's a different deal altogether and probably should have been included in the original post.

Yes, if you are in an emergency situation and need to limp home, it is safe enough to pull the cats. Loud AF, but it can be done for a short period like that.

Misfire plug 6 , o2 fault , that's all I remember .
It was hot i placed a piece of paper near it and it curled like hold near a fire

I'm sorry . I will reword the original.
What would be to long and do you suggest a preferred brand then stock cats ?

 

[Dirtman]

Well the fix is to find out the issue first. Need to get the actual codes (numbers). Autozone or places like that will do it free. Write down the numbers not what the guy says it means. A misfire dumps excess fuel into the exhaust, excess fuel burns up cats.

To run just with an open Y-pipe? Get home and shut it down. Fix it right before driving any more.

In theory, as far as safety for the vehicle you COULD run a test pipe in place of the cat indefinitely.

Dirtman is right though. You need to find and fix the initial problem that over-heated the cat. If it is melted you dumped a LOT of fuel down the exhaust. If it is crumbled/collapsed then it could have been an age related failure.

Some aftermarket scanners will say O2 fault instead of listing the codes. O2 out of range is a symptom, not a diagnosis and probably indicates a rich(in your case) condition due to cylinder 6 misfiring. I've seen cats glow like stop lights and be fine once they cooled down but if you need them, Walker sells direct fir replacement cats for a lot less than Ford charges.

So keep in mind I have disconnected bank one sensor 1 .
Codes are .
P0155
P1151
P0122

Misfire code would be a p0300-p0306 you said it had a misfire but those codes aren't there. The last code is TPS sensor.

My husband said he did the plugs last weekend when he changed out the thermostat ,waterpump , tps . I was hoping the computer would clear in it's own for the tps . Looks like I need to clear and get some miles back under her.
Also the o2 I pulled was oe ford .
All components we have been changing have been oe with ford stamp .
