I have a 2012 F-150 V8 5.0L (COYOTE) and it has 67,000 miles on it. It jerks when I hit the gas from a complete stop. No codes have been thrown up. It doesn’t jerk any other time. The rpm needle fluctuates a little when sitting in park but not too bad. Could it be dirty due injectors?

 

Try greasing the slip yoke.

 

Yes, rule out driveline issues first, also check the u-joints. With 67k, change the spark plugs if they are original. I doubt it's injectors, but a couple bottles of Techron in the gas sure wouldn't hurt.

 

why did my brand new Coyote do a Sudden Acceleration after a loud explosion sound and then full throttle on it own? Any answers
