Has anyone else been having trouble with their engines idle reving up to 1100 RPM's by itself? You turn the engine off and turn it on again and it returns to its normal range of about 685 RPM. The dealer says there is nothing wrong. Ideas anyone
im a tech at a ford dealer, rich is right, its what they call the regineration cycle were it super heats the particulate filter in the exhaust system to clean it, its normal. you may notice a lack of power also
I can hook you up with a DPF delete setup, it will stop the regen and give you way better fuel mileage. I just hope you're not a fan of that handy little warranty that came with the truck??
