Here's a pic of the worst of the spark plugs I replaced yesterday. As I learn more about cars while attempting to fix my Liberty I realized, yesterday, that I certainly overlooked replacing the spark plugs. I'm sure this has fixed my low start up idle problem and I'm sure a host of other problems. But in the name of learning, I'd love it if someone would throw out a guess about how old these might be. My wife and I were gifted the car with about 125k on it and now are at 145k. I don't know when the spark plugs were last changed but not since we took possession. The ones I pulled say NGK R. I replaced with the NGK V which seemed, from my research, to be OEM for the 2004. Am I wrong about that? Also I'm debating going back in and checking the coil packs which of course I neglected to do when replacing the spark plugs. And finally i didn't check the gaps on the new plugs, just assumed they were gaped properly. Anyone have any experience with the NGK V's and the factory gap? From what I could glean online, a few reviewers said all the ones they checked were gaped right out of the box...thanks in advance!
