Open the full vehicle complaint log (all categories)When I accelerate after a stop my truck starts jerking when shifting thru lower gears and the check engine light flashes. To increase my speed I have to slowly press the gas until it shifts thru gears. After it shifts thru the lower gears it appears to be okay. It doesn't do it at each stop but is now happening more frequently. I don't know if it's a transmission problem or fuel pump. Current mileage is around 62000. If I'm on the highway it will sometimes start jerking while the using cruise control and I have hit the brakes and take over acceleration. I've now parked the truck because dealer cannot get to it for 3-4 weeks.
Excessive fuel in the oil. Oil smells of gas and is diluted. Almost a quart high at 3000 mile mark. Dealer and Ford admit this may be an issue on some engines but it is supposed to be normal??? We installed a pcv catch can and it will fill up with fuel in about 800-1000 miles. That is almost 8 ozs. The included photo shows oil at about 4000 miles. The second hole you see in the dipstick is above the full mark.
