Step by step instructions would be best.
The upper plenum will need to be removed on the 4.0 liter. Once the plenum is out of the way the coils can be removed and the plugs replaced.
on the 3.8 liter remove the plug wires from the plugs one at a time and replace that spark plug. Place the wire back on the plug as soon as it is installed and move on to the next.
