f250 abs

My 1992 f250 2wd with the 300 has both abs lights on and feels down on power and shakes a bit going 40 to 60 with light throttle just to keep the speed but when I unplug the ABS computer it doesn’t shake the lights are of and on but mostly on

i already replaced the rear speed sensor with a doorman one and was fine for a wile but they came back i will check the resistance tomorrow and will report back

You only have one abs light. The other is the normal brake light that tells you the parking brake is on or the brake fluid is low. Did you check the quantity of your brake fluid?
When you say "shaking", are you implying that the engine is missing?

My resistance of the rear spead sensor is 3.31
when I un plugged my abs computer and drove it i couldn’t get it to shake and with my red brake light my fluid level is good. My float is good. It’s a new master cylinder. I haven’t checked the parking brake yet I know it engages in disengages. I use it every time I park I haven’t been able to find the ABS flasher light port, the one under my glove box where I’ve seen for others is blue and yellow

You will not be able to check for RABS codes until you resolve the Red brake lamp cause.
