Multiple codes

I have a Doosan G30P-5 MM-00227. Gm 2.4
We just rebuilt transmission and my guys never noticed if engine light was on before we did it.
Did transmission and drive it around. Lots of codes. Won't clear with 10 pump.
Seemed to run ok.
Double checked wire plugs and grounds.
Looked for opens.
Never unplugged ECM.
It now backfires once I. A while and hard start.
Now for the codes.
151,221,291,331,332,353,381,711,712, 717

Swapped MAP as I had one and no change.
Vacuum lines look good and not plugged.

Help

Thank you in advance

Fact of the week
The use of "hello" as a telephone greeting is attributed to Thomas Edison. He is said to have suggested it as a simpler alternative to other greetings, such as "Do I get you?" or "Are you there?".
