My 1996 Lincoln Towncar Signature Series bogs down when I add any load to the gas pedal. I have to feather the gas barley touching it and it will slowly go through all the gears and get to 55 after 3-4 minutes. If I push the gas down further it bogs down and won't go the the gears again until it gets down to 34 miles per hour. I've changed fuel filters I've cleaned the mass air flow regulator with the special spray that cost too much. Per your video suggesting I should do it to improve gas mileage. I've just purchased a 50 dollar oxygen sensor since the car code said I needed one. Have you heard of this before. It feels like if you push the gas a stone goes up and stops the fuel from going in but if you gently touch it it works because there's not enough pressure to lodge the stone into the fuel line to block it. I'm at a loss. My dad's been a mechanic for over 50 years just retired had a heart attack he's not up for it. Please help Scotty. I've been paying registration on it for 3 years now and it sits there just for emergencies. It's my third 1996 Lincoln Signature I just love them. Just had the upholstery re-done for goodness sake. If I can't fix it soon I'll have to sell it and a whole lifetime of spare parts I've accumulated to take care of anything. Thank you for your advice Scotty. Looking forward to hearing what you think.

This sounds like a fuel pressure problem. I read through somebody with a 1994 Lincoln Continental having a possible fuel delivery issue, you can read the thread here: https://www.lincolnsonline.com/forum/showthread.php?t=82041
I also Googled what the fuel pressure should be at idle, Google's AI says between 35 PSI and 45 PSI. Cross-referencing the forum seems to confirm this.
The simplest thing is to check the fuel pressure with a gauge you can rent at AutoZone.

What code? There's no code that says you need any particular part, codes point to a condition that exists which usually will have several possible causes. Did you test the sensor before replcing it? Did you install an OEM sensor? Have you analyzed live data for problems? Checked for clogged catalytic converter? How old are spark plugs and filters? Have you checked fuel pressure?
There's no getting around the fact that you're dealing with a car nearly 30 years old and almost anything could be wrong, there could even be multiple problems.
