spark plug question (93 SE)
I'm out working on my car trying to figure out why it sounds like it has a misfire, idles rough, and gets horrible mpg. I've got the coils off about to be tested when i find my multimeter. Just for the heck of it, I pulled the plug out of the cylinder that is farthest to the right in the back, and it has gone from a gap of .060 to .082 in just over 20,000 miles. There is hardly any tip left on the spark plug. Pics are coming in a minute. Does this mean i need new plugs?
