Out of no where my Expedition performed this transformation (actually the wifes car) not much fuel in it (surprise)this started right after the last time she fueled it. I put some additive in the tank and 10 gallons of fuel. Can’t rev the car past 3,000 rpm’s and driving it is out of the question. Any ideas?
