My 2003 ford econoline e-150 jerks at all different speeds

Customer Question

My 2003 ford econoline e-150 jerks at all different speeds intermittently. All the coils and spark plugs have been changed
JA: Sometimes things that you think will be really complicated end up being easy to fix with a Ford. The Ford Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: There is no check engine light on. It doesn't do it all of the time but it does do it quite a bit at all different sppeds.
JA: Are you hoping to fix this yourself?
Customer: My friend is a mechanic and we thought sparks and coil would solve the problem but it does not. His diagnostic machine shows nothing.
JA: Is there anything else the Ford Mechanic should be aware of about your Ford?
Customer: not that i can think of at this moment
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Ford Mechanic about your situation and then connect you two.

Hello does it act like you are driving over a washboard road or does it feel like an actual misfire?All the coils have been replaced? Does his scan tool have the ability to look at OBD II Mode 6 data? How many miles are on the engine?
