Furnace struggles to ignite after new inducer motor
First off, I am going to assume you replace the inducer motor and wheel with the proper replacement. They are sized exactly to provide enough flow through the heat exchanger while maintaining a negative pressure in the vent pipe. 
That said, you are having a problem with flame proving. You cleaned the flame sensor but unless you have extremely dirty gas it is almost never dirty enough to cause a problem. Make sure the white wire is connected all the way from the flame sensor to the circuit board. If you have a multi meter with micro amps you could unplug the white wire at the flame sensor and plug a lead into each wire in series. You should get about 4-5 micro amps with the furnace running. If you don’t, it is either a bad ground or a bad circuit board. Usually a bad circuit board but I have seen all sorts of grounding problems from no ground to the furnace to a bad house ground allowing too much voltage into the ground circuit. I have also seen Payne (Carrier, Bryant, Day and Night) furnaces work for 15 years with a bad ground and then stop working. Once the ground was fixed the furnace continued working fine.
