Hello, welcome. My name is***** will do my very best to assist you with your question. I apologize if you have been waiting long for a response.

The engine that was installed, did it come from the same year of vehicle?
Also was the ecu reset after the install?

Thie issue that you are currently having is coming from the ecu, the ECU is not communicating properly with the be engine. What will solve this problem is the ECU bring reset, this will need to be done with a diagnostic tool. Thank you.
