my lude just recently started to bog and hesistate.. it usually drives normally for a while then it just starts to bog, it will not accelerate unless i floor it.. if i try and gas gently it juss bogs/hesistates... like for instance i'm on the freeway doing 60 steadily and all a sudden it just bogs . it won't pick up unless i floor it.. so far i've changed the cap,rotor, and spark plugs.. i'm thinking either the distributor is going out or the ignitor.. what you guys think??
