Im out driving , cars all wormed up , Doing lets say 60 , and want to pass . Its a 5 speed . As we gas her up, it starts to like buck. Go around the other car and get back to 60- 65 , its fine with never a problum . So what is it . I changed the Cam and Air Temp sensors . Could this be the crank sensor , I hope not. If so whats the trick to that one . Some say , wires or plugs . Their not that old . Thanks for any input . D.W.
