I recently swapped the bad 3.5L non turbo motor out of my 2013 For Explorer with lower mile 3.5 non turbo out of a 2015 Explorer. My Check engine light is on and it seems to be sluggish have to really mash the throttle down to get it to change gears as if it's almost in a limp mode. I haven't drove it since September of last year but it was never sluggish before... once you have it going it runs fine changes all the gears... just seems like it's something missing. Computer need to be flashed for the swap??? Any help would be greatly appreciated. I have not yet checked the code for the CEL.
