It has begun to "stumble" when light or heavy acceleration under load. it takes anywhere from 8 to 20 miles to start it. The ambient temps have been relatively mild (80-87F). I have done all that I can think of to do (minor things): cleaned up all elec connections, cables, ground straps, changed plugs (which seemed to resolve only to have it resurface a day and 20 miles later. The plugs I removed looked textbook perfect.) I suspect coil for no good reason.
