Gap Change???
Ok So the truck has had a rough idle the past couple of weeks. It has been in the 10-30F temp range here the last few days. Thought I might be having injector problems so I ran a bottle of cleaner through; the idle smoothed out for a couple of days then it came back. So, out of curiosity, I pulled the sparkplugs to have a look at them. They are autolite APP 5224. They have about 25,000 on them now. The stock gaping is .40, but all of mine were in the .65-.75 range. Yes, I gaped them to .40 when I installed them. What would cause the gaping to change?

eh, my truck doenst get tortured very hard, so I think that 25000 on one set of plugs is still minimum.
Here are some pics of the plugs, excuse the quality since I can't seem to find my good camera.
I know, I thought it to be weird too, thats why im asking .

I did it myself, and it wasn't the first time doing it. This is bizarre. Ill put them back in tomorrow regaped, and see what happens. I am wondering if its the platinum that's giving me issues. I know plats aren't necessary for our trucks but that's all Wal-Mart had

The platinums shouldn't burn up as quick as the copper. That's really weird. Maybe you just got a bad batch of plugs or something.
