I'm getting a misfire, no CEL, but it can be bad at low RPMs under power (like taking off from a stop on a hill). I'll be doing a big tune up, without the valve adjustment. New plugs, wires, and a lot of other stuff. So...
I've read that our plugs need to be gapped at 0.043" (1.1mm). If my gap tool only does 0.040" or 0.044", should I go for the tighter tolerance? Is that close enough to not cause any issues? As the ground wears down, does the closer tolerance give me a little more life in the plugs?
I've read people saying "you must gap your plugs" and others saying "do not gap your plugs out of the box or you will ruin them"? What the...?
When I was young, my dad showed me how to gap plugs. We would take the plugs out, clean them, gap them, and put them back in. Have things changed as far as this is concerned? I don't hear about people re-gapping their plugs any more; people buy new ones. Why can't I take my current plugs out, re-gap them, and use them longer?
I will be using double-ground platinum Denso plugs.
