Any thoughts on whether the spark plug issue on the 2005-2007's is caused by time or heat cycles? Say I find an '06 with 5,000 miles, would it be more or less likely than a higher mileage engine to have a problem? I'm thinking the issue is corrosion related, so the time element would drive it, but then sometimes heat can accelerate corrosion of parts so a higher mileage engine would have a worse problem with this. Any thoughts?
