Codes p0171 and p0174 until I reach 110km/h. Then it starts to lose power and won't climb even the slightest hill. Downshift to 4th, throttle to the floor, still losing speed. Clear the codes (code reader stays plugged in) and engine power is restored but only for 1 or 2 seconds if I keep my foot to the floor. Longer if now downhill and little throttle is used. Now p0131, p0137, p0151, p0157, p0171, p0174 all at once. Haven't been over 130kmh (couldn't when I wanted to) with this truck since I owned it.
