What is the correct spark plug gap on 2003 gmc safari V6 4.3L using autolite platinum plugs


If you have the owners manual you should find the gap specifications there. Otherwise using a standard plug chart at any self serve retailer will provide the compatible plug specs.

.060 is fairly common pre-gap but check your owners manual to be sure.

Had the spark plugs and plug wires changed on my 1994 GMC Safari minivan, and now it runs very rough. If I stop, the engine shuts off. Backfires a lot also. The whole van shakes bad going down the road....


If your Safari did not expecience these systoms prior to you changing the plugs and ignition wires, then you may have crossed two or more of these wires when they were repalced.

How do change my spark plugs for a 1994 gmc safari?


Hello dechile1313: My name is Roger and I can help you. You will need to remove the engine cover from the inside to gain access to some of the spark plugs. The other plugs are accessed better from the wheel Wells. Raise the front end up to drop the tires down. Reach through the wheel well and lift up the rain shield you will see the spark plugs. Be sure and twist the plug wire boots back and forth to keep from braking the t plug wire ends. Please rate the quality of this reply. This lets us know you received the information you requested. Thank You for using FixYa. Roger

Spark plug issues on GMC Safari early 90's.


The simple fix would be to get a ratchet and spark plug socket and tighten them. First remove the plug wire from the plug and then use the socket to tighten them one at a time so you do not get the wires mixed up as to which one goes to which spark plug. Tighten them slowly to avoid breaking one of them but do not over tighten them either.
