i have a 2000 ford f-150 134000 i have replaced fuel filter coils injectors and plugs but when i go down the road and give it any decent amount of gas it bucks pretty bad i was told it could be a vaccumn leak off the manifold but i am unsure what to do it didnt wanna idle right in the beginning and now it seems to idle fine but going down the street is a different story also sometimes locking my hubs in gives me problems could it be the main vaccumn off the manifold that is causing this bucking and probs with hubs??? thank you for any help
