Hello I just got my truck back together it had a cracked head and I have been driving it around for about a week now anyway when the truck is under a load it will ping like crazy I know it did a little bit when I was going up hills before the major repairs but it is doing it all the time on the freeway. I took out the spark plugs and examined them they all seemed to be in good shape but one on the driver side was loose could that be the cause? Does this engine not like copper plugs? Also the truck did sit for awhile but there was a quarter of a tank left of the old gas so i just refilled it with new gas.
