    Hi Welcome to the forum.
    I presume you changed the inlet manifolds over on the engine. As even know the engine codes are the same, there are different parts. MAP, EGR, IAT.
    You could try the relearn on the peddle and throttle body. By disconnecting the battery wait 30mins. For all the ECU to go to sleep. Then reconnect. Start the car on the key but don't touch the throttle pedal, and let the car idle for 2mins.

          It seems odd to me that it worked to start with, but within two days, started to play up.
          I am wondering if there is an electrical connection that has become disconnected, or has dirty contacts.
