I just bought a 1999 Jeep Grand Cherokee Limited (Quadratrack) with a bad 4.7L engine. If I acquire a used 4.7L engine from another Jeep or pickup or whatever, will this be a "plug and play" installation? Is there a different tune loaded into the ECM for the different vehicles and will I need to keep the Cherokee's ECM with the vehicle (ie, Jeep ECM onto replacement engine)? Does anyone have any suggestions what to look for when shopping for a used engine. Do I need to stay year and model specific or can I use any 4.7 from 1999 to 2004 era.
