316.79108. What is the proper gap for the sparkplug?

Hi Gary!

If you got a CAR and not a truck, there are a few things you need to pay attention to when replacing spark plugs.

You need to make sure your spark plugs are the issue for whatever the problem is.
Take a 16mm SPARKPLUGS spanner (it's a special sort of tool that you buy in the shop, unless you have it, don't bother to try with anything else, or your could do some damage), unplug one of the cables attached to one of the sparkplugs (make sure you don't unplug more that one, so you won't mess the order), take your magic tool (sparkplug socket spanner or whatever it is called) fit it on top of the sparkplug, (listen for the clicking) and then twist it left until the sparkplug is out.

Have a look to your sparkplug, and see if there is any carbon on it (if it's black, it has to be replaced/sandpapered)

repeat the operation to the other (alledgedly 3) sparkplugs, naking sure you DO NOT MESS UP the order of the cables that connect to the sparkplugs.

If finally you've decided it is time to replace the sparkplugs, under NO circumstances, replace less than ALL of them. (unless you replace them on the car of someone you don't like)

Check plugs for proper gaps check for a black carbon trail on one indacating a cracked porcilin then attempt to carefully pull sparkplug wires off with a sparkplug wire puller. If you don't hear sparking there is an issue between the wire and or coil

The correct sparkplug gap for a 1995 buick parkave is .060 gap. good day

get a diagram online for the proper sparkplug wire locations and make sure they got put pack in the right firing order. Sometimes it is easy to accidently get them mixed up. Also I was acutally given the wrong sparkplugs from the autoparts store the other day. I went to find out the proper gap setting online and found out the plugs I had were not for my vehicle. Checking the gap on plugs is important before you put them in because sometimes they get dropped and the gap is wrong when you get them out of the box.

Those are as easy as they come these days. Mark each spark plug wire with a piece of tape with the cylinder # written on it, so as not to mix up the wires. Remove each spark plug wire by firmly grasping the wire by the boot (do not pull on the wire) and twist it back and forth a few times while pulling slowly. It should pop off without a great deal of effort. If it is seized and it breaks, you will have to replace the wire, or at the very least replace the terminals (if you can get some). Use an air hose and blow around the base of each spark plug to dislodge any loose dirt that could fall into the cylinders (not absolutely necessary, but a good idea). Remove each spark plug with a spark plug socket and extension and ratchet (I forget which size socket, it's either 5/8 or 13/16). Check the gaps of each new spark plug (typically around 0.035 in). re-install each new spark plug by hand (do not cross-thread them) and once you have ensured that the plug is threaded in properly, tighten the plug until it seats, and then tighten an additional 1/16 of a turn. Repeat this for the remaining plugs. Re-install wires to the corresponding spark plugs. You're done!

With you hood open and you are standing in front of the car sparkplug wires need to be removed,i suggest you remove them one at a time, under each wire the sparkplug is threaded into the cylinder head,using a 5/8 sparkplug socket remove the sparkplug and replace it with new properly gapped sparkplug.Note:if you remove all sparkplug wires at once the factory wires are generally numbered 1 2 3 4 the sparkplug closesed to the passenger fender is #1 and the one clossesed to the driver's fender is #4.Standing in front of vehicle the PCV Valve is located between #3 and #4 on the backside(intake side) of the engine fitted down into a rubber hose

the sparkplugs are shipped with the propper gap setting *DO NOT CHANGE IT"

if its been altered, place a penny in the gap, and thats the space it should be gapped.

Spark plug gap is .025

As for the air gap in-between the flywheel, and magneto, I generally start with a piece of notebook paper in-between them.

After the bolts are snugged down, turn the flywheel by hand to spin the paper out.

the plugs you need are ac delco you can find the replacement proceedure on autozone.com vehicle repair guides

it appeares that your vehicle has what we call a flat spot.if you changed the sparkplugs reasently the air gap setting might be incorrect.if not changed sparkplug can be worn replace.proper airgap setting 1.1mm
