when I turn on the heat I smell like burnt oil. and then the car starts to jerk

Hello, This is certainly a strange problem to have, and I really would need to see this vehicle to figure out where the smell is coming from, and why the car begins to jerk, as these issues are not typically related to the heater. Let me know what questions you have, and here is a link in case you prefer to have it diagnosed: http://repairpal.com/ford-within-10-miles-of-fergus-falls-minnesota-56537
