Happy Thanksgiving! My Toyota Highlander 2005 has a more than normal amount of smoke coming out of the exhaust pipe coupled with a knocking noise (that goes from louder to softer) upon starting the car. The smoke does not go away. There is a strong gasoline smell also. What is happening? I'm afraid to drive it. I'm a single mother and low on funds so I'm hoping this is not going to be an expensive fix!
Also the heater is not working in the car, only the A/C.
