Icon4 New Computer/Tons of codes?

(UPDATE) TRUCK IS BROKE DOWN OUTSIDE SOMEONES HOUSE TRIED NEW BATTERY TRIED JUMPING HER TRIED FILLING WITH GAS EVERYTHING AND NO LUCK SHE BROKE
Hey guys so I put in a new computer into my 1994 ford ranger and started the truck she ran fine for about 5minutes then she dropped down to about 800-900 rpm the check engine light was on instantly when i turned truck on wasnt like that before with the old computer that had leaking capacitors I was wondering if these codes could be from the computer being bad, or not the right computer or something this is what I got
The computer I had the numbers on it did not match anything I could find so I got a new computer from autozone but the numbers are different but it was programmed for my VIN and Mileage
116 - Coolent Temp Sensor out of self test range
114 - air temp sensor out of self test range
629 - torque converter clutch solenoid circuit failed
566 - 3-4 **** solenoid circuit failed
512 - keep alive memory test failed

I unplugged battery for about 20min to see if codes would go away and nope and when I started my girl she sounded really rough in the engine area like the engine was trying to jump out the truck any advice?

What engine is in the 1994?

629 - torque converter clutch solenoid circuit failed
566 - 3-4 shift solenoid circuit failed

These are for an automatic transmission, is your truck an automatic or manual trans?
if manual then you got a "new" automatic computer so it will always have those codes, and CEL will always be on
Manual trans and automatics used different computer software

116 - Coolant Temp Sensor out of self test range
114 - air temp sensor out of self test range

Shouldn't cause running issues, but check connections on these two sensors

512 - keep alive memory test failed <<< is because you have unhooked battery recently, the computer has power all the time to keep what it "learns", like presets in Radios
When you unhook the battery is loses that learned data same as the radio loses its preset stations
