So I did a fuel pressure test all good there I pulled plugs wires checked and replaced I did notice when I took the air filter lose earlier while it was running it didn't take much at all hardly any resistance to stick my hand in there and stop the air flow it almost immediately died. Don't know if that helps. I'm still at it will give more info when I get to it. Thank you so againTrue indeed.
Un-metered air getting past the Mass Airflow Sensor will make you dump fuel.
Glowing cat is textbook vacuum. These plastic intakes are known for cracks, leaking gaskets and melt holes. A hole will be way too small to supply air with the intake plugged with a hand. Give it a real good inspection, around the seams especially. A smoke generator comes in handy in such an occasion.[/Q
Thank you. I actually just finished everything that I'm capable of doing. I was told about a smoke generator and that will be the next direction I'm headed. It's so confusing. I have looked and looked at every possible scenario to make this happen after putting everything back together it does run better when put in drive but the lack of power and cat still getting hot enough to glow is still there. Any recommendation of where to get an affordable one. Thank you buddy I'm taking all the help I can get. To fix this problem. And I feel as I'm getting closer.Glowing cat is textbook vacuum.

@Block MakerI'm wondering if in the midst of all the repair work I dropped one end on the connector to the O2 sensor after the cats in old oil and tranny fluid I cleaned it the best I could before finally getting electrical contact cleaner, yes it was plugged in before. And I thought I had to take the exhaust apart to get my tranny out so flange coming off the block was taken loose it has been tightened but it was rough. And I also noticed today that there was a crack more than likely from my knee is in the plastic cover on top of my engine. It's not broke just cracked. Could any of these things made my cat go bad. I know I'm not the best at fixing but I'm learning and try to not repeat my mistakes. Thank you for your time
That's a nice theory but no, it's not so much "textbook" (there are many other possible lean misfires and intake manifold gaskets themselves are more common so absolutely not textbook) just one possibility but more importantly, quite a coincidence for it to happen not before, but right after a tranny swap and ??? who know what else.Glowing cat is textbook vacuum.

I cannot say I remember that one but if this solves the problem....
You would think the harness connectors would be arranged where that can't happen.
To make life easier for the OP would you happen to know how to tell the difference between R & L on the main harness?
Noticed that the OP has a 99.
I'll go dig out my Ford Workshop electrical manual and see if the electrical section list a different color wire for L & R pre-cat.
muffler or Catalytic Converter?I stop the car the muffler is glowing red hot
muffler or Catalytic Converter?
if it's the Catalytic Converter
is it the front or rear Catalytic Converter that is hot?
@Tech By TradeThis is getting intriguing.
