Missing and sputtering with data log

Started missing and sputtering a week ago. The issue is most notable when I am in a steady cruise. Ran a data log driving around town.

Any ideas on what the problem is?

Thanks

Re: Missing and sputtering with data log

Your other post indicated you were running a conventional plug, and had 21K miles on them. An iridium plug would provide much longer life.
