...try to locate non ethanol fuel in your area. Out here in the hinterlands of the Willamette Valley there are two within 20 miles. They both sell non alcohol premium. It lasts better and gives much fewer problems in general with fuel.
That is regardless of what the problem is but especially if it's fuel related. When you are out and about and need fuel and have to take alcohol, drain the tank into your auto sooner rather than later. IMHO...eh?
