i'm curious about spark plug replacement - and how often it should be done for older vehicles. Specifically my Explorer is 22 with almost all original parts. I'm only the 2nd owner and it's been in good care since 2006.
in general spark plug replace is at 20K. i'm only at 17k and i've got a shuddering between 1500 - 2500 RPMs in 1st, 2nd and 3rd gear. i realize that spark plugs might not be in the issue here, but i thought i'd ask around and see what the forum's experience with older Explorer models has been.
