i might think my DIS is going bad and so does Back n black bird. i posted my problems 2 days ago and all i need to no is what all does the DIS do for or cars.
Basically its the distributor it makes the plugs fire in the correct order, when that starts to go bad, the plugs don't fire at the correct time causing it to jump and buck. Its basically a "distributor" found on all pre-electronic cars
