Why would it accelerate and alot of smoke releases

Hello, smoke of different colors tell different stories. White smoke is of condensation or water in the crankcase. May or may not be a sign of concern. Black smoke is typically of carbon - fuel - excessive fuel consumption. Blue smoke is oil consumption. That's all generally speaking, but a good start. Have the smoke looked at by a shop near you who can give you realistic first hand advice. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
