When I'm at a complete stop and start to accelerate and go or on a freeway and try to accelerate, my engine starts to jerk and miss like crazy. The check engine light is not on so I really don't know whats going on. I had an auto repair shop put it on the diagnostic machine but he said nothing came up as a problem. Now I'm stuck with no answer and afraid to drive my expedition. Can anybody tell me whats going on and/or what I can I do to fix my expedition?

I'm surprised that the check engine light didn't come on. It sounds like a misfire. When was the last tune up? Have you ever checked the fuel pump pressure?

Let me know. Also, I need to know which engine you have.

My truck has a 5.4L engine and no I haven't had a fuel pump pressure check. I've never had the spark plugs changed yet but I will.
