Re: For those who drive a Hemi 5.7
Welp... new spark plugs in as of yesterday. I've only put about 25 miles on it so far, but my MPG is reading 5.1 now. The rough idling has ceased to be an issue with the new plugs, at least. I'll check back in after putting in some real miles. Trying to avoid jumping to a conclusion after such a small sample, I was just hoping to see an immediate uptick.
