Well first you will want to get the right size spark plug socket , the rigt sized one for your envoy and then next you will want to remove one spark plug wire at a time so you do not cross any of the wires or if you do you will mess up the timing for the envoy now how to remove a spark plug wire, look first at the plug wire and then gentky twist the wire on the end that goes over the spark plug and carefuly pull back but do not break the wire, next with an extention and the socket put the socket over the spark plug and turn the plug counter clock wise until you have removed the plug and then put the new spark plug in and place the spark plug wire back on the spark plug and just repeat the prosses on the rest,agin do them one at a time that is how I change spark plugs and wires and i have been doing it for years.
