Guys,
I have been relocated to Los Alamos NM for work. I left the Raptor at home due to apartment dwelling status currently. I brought my 2014 F150 Screw with the 3.5 Eco Boost. I did all the preventive maintenance before I came. New plugs, coil plug boots, oil change , new brakes, new shocks, tires, alignment. Everything I could think I would need to get me thru the next year. As soon as I hit higher altitude than Oklahoma my check engine light came on. This has happened every time I have brought this truck to NM since it was new. My dealer said it was just the attitude change mess with the air fuel ratio. (Not sure I'm drinking this Kool aid)......In the high mountains yesterday it is winding and uphill at a speed of 25 mph. Turbos seemed to load up and caused the truck to shutter. I had been driving around quite a bit this day. Is this a pre detonation issue. Do I need to run 91 octane or is there another issue I should be concerned with? Thanks for the advise
