Hi all. Recently acquired an 89 4R, 22re with a locked motor. Found a replacement, and have installed it. The engine runs sluggishly, stumbles upon acceleration, smells very rich. I get codes 22, 24, 31, 41, and 51. Do need to start out going through the checks for every circuit and sensor, or does anyone have another suggestion. I have looked many times, but can find no wires or hoses not connected. The engine was from a 91 truck, 22re, and I used the 4R plenum with the 91 truck intake and injectors.
Any help steering me in the right direction would be very much appreciated.
Thanks
Rod

 

Which engine are we talking about?

 

The motor is a 22re.
Thanks

Look for common sensors/circuits in the codes:

Then on the straight forward codes, check out the sensor(s) indicated and see what you find. For example:
