Shon: Prolly because of your E85 mix. What's your ratio? Yep, looks like you went into limp mode.
I was just in Flagstaff at 7000 foot elevation. My car was NOT happy. I was running approx E30 at the time. My car went into limp mode and I couldn't get back into my JB4 either. Down buttons did nothing. So, I restarted it and ran 3 or 4 new WOT to relearn. Once I dropped to 3000 feet, it seemed to be running better. But, still...finding E85 in AZ was a b!tch.
I'd double check with Terry and see what he says.
