Why does my Buick sputter, accelerate on its own and is hard to stop?
A couple days ago my 99 Buick century suddenly started sputtering, backfiring and most the time will accelerate hard on its own while backing up, or pulling off from stop. Its cut off a couple times now at red lights. My brakes suddenly became hard to push in as well and is becoming harder and harder to stop. I know the two probably aren't connected, but can someone please tell me what it may be? Thanks!
Es esta una buena pregunta?
