Those codes erase automatically after the problem no longer is present. I mentioned that previously; it will take 50 engine starts after the problem is gone.
No permanent damage should occur but until the E85 is used up, there will likely be a sag or hesitation on acceleration, particularly when the engine is still cold. Your fuel mileage will drop by about 30 percent. For use of E85 on a regular basis, Chrysler is very specific about the type of engine oil that is used. They also recommend alternating between E85 and unleaded regular every other tankful.
I've been through two service manuals and the Chrysler web site, and I can't find any information on flex-fuel designations, but as I recall, there should be some kind of sticker by the gas cap that spells out that E85 is acceptable. Also look at the emissions sticker under the hood. If there is any mention of anything that must be suitable for flex-fuel use, it is likely your engine can run on it.
