It's hard to tell what you mean, with such bad spelling and grammar. By the way, it's accelerator, not excelerator, though the word could sound like that. If the car has a manual transmission, the clutch much be worn out. If automatic, check the transmission fluid level. It should never lose fluid and if the level is too low, there's a leak- the transmission needs enough fluid or it won't work. Seems like you tried to say the engine was not revving (ribbon, you said). There's an altogether additional problem. Have a mechanic look into this.
