Why you want change spark plugs wire .THIS IS LAST THING TO CHANGE.Change spark plugs I agree.

Instructions

• Locate the spark plug cables along the top or the sides of the engine, depending on CR-V model. Once the engine cools, use the trim panel tool to twist the spark plug wire at the wire's boot, which is the larger rubber portion located on top of the spark plug.
  
• 2Pull back on the spark plug wire to remove it from the spark plug.
  
• 
  
• Place the socket on top of the spark plug and turn it counter-clockwise to unscrew and remove the spark plug from the well.
  
• 4Rub anti-seize lubricant onto the new spark plug threads and on the tip of the spark plug.
  
• 5Insert the new spark plug into the well. Manually turn the plug clockwise to thread the spark plug into place.
  
• 6Test the tension on the plug with the tension testing tool. Adjust the tension as needed. Honda CR-V spark plugs generally need a tension between 10 and 15 foot pounds. The spark plug's packaging indicates its suggested tension.
  
• 7Replace the spark plug wire, turn it from side to side and lock it into place. Continue the process with the rest of the spark plugs one at a time until all of the spark plugs are replaced.
  

1. Pull the hood release lever located under the dashboard.

2. Walk around to the front of the car, reach under the hood, find the latch and squeeze it. Open the hood.

3. Find the spark plugs, located in a row along one side of the engine (on an in-line four-cylinder engine) and attached to thick wires, called spark plug wires. Cars with V-shaped engines (which can have four, six or eight cylinders) will have spark plugs and spark plug wires on both sides of the engine.

4. Change one spark plug at a time, always putting the plug wire back on before changing the next spark plug.

5. Pull off one spark plug wire where it attaches to the plug. There is a little rubber boot at the plug end of the wire; pull on this part. Pulling higher up on the wire can damage the spark plug wire and cause it to separate.

6. Blow or wipe away any dirt or debris around the spark plug. You do not want anything to fall into the cylinder while the spark plug is out.

7. With the spark plug socket and a ratchet, remove the spark plug by turning it in a counterclockwise direction. You may need an extension for your ratchet if the spark plugs are deep-set or not directly accessible. Ratchets with flexible heads are especially helpful for hard-to-reach spark plugs.

8. Check the spark plug to make sure it needs replacing. A good spark plug should be lightly coated with greyish brown deposits. If heavy deposits are present, if the spark plug is black or if the electrode or core nose are damaged, the plug needs to be replaced.

YOU NEED A SPARK PLUG BOOT PULLER TO REMOVE PLUGS WIRES.

Hi: If this is your 1st time to Change your Spark Plugs, I recommend that you First of All Get the Correct Spark Plugs from your Auto Parts Store, Then Locate your Spark Plug Wires which run from your Distributor Cap to your Spark Plugs.If you have a V-8 There will be 8 if you Have a V-6 Then You'll have six Spark Plug Wires and 1- COIL Wire which is located in the Center of your Distributor Cap to your Coil. It is the Shortes Wire.I Recommend you ONLY do 1-Spark Plug at a Time, This will Prevent you from getting any of your wires Crossed which will Cause your Engine to Run Rough ,Back Fire or Not even Start,So just Pull off 1-Wire From Spark Plug and one Wire From Your Distributor Cap, You'll Need a Spark Plug Socket Probally 5/8th in. And a Ratchet and 2- Different Size Extensions to beable to reackh all your Spark PlugsNOTE!! Buy you a Spark Plug Wire Tool there not very Expensive but well worth it,This was you Can Pull the Wires with out Damaging Your Wires.And you Might Want to Put NEW Spark Plug Wires On as well, If So and I do Recommend This. And Again Just do 1- Wire and Plug At a Time So you'll know you Have Not Crossed any Wires. Hope This Helps You ,Please Respond by Voting on This Problem And How it Helped You. Thanks From WYOCWBOY

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.
