Since we're talking about the RCM solder fix, I'm curious if this problem is unique to the older model Xfires, or is it a problem that crops up across all model years.

I ask the question cause most times when I see this issue posted, it seems to be more common with the 2006 and older cars (although I could be wrong).

Maybe it's because the older the year, the more mileage, and the more vibration that might impact the joints.

Comments welcomed...
