Have a 2014 scion xb and just installed new throttle body a month due to a scanner code P2109 but car still jerks Mechanic's Assistant: Just to clarify, what's the exact code? And have you tried to reset it? Bad idle, high RPM when car is first started in the morning. I slow down at a stop light or sign and engine shakes a bit then shuts off. Mechanic's Assistant: Are you fixing your xB yourself? What have you tried so far? It reads P2109 throttle/pedal position sensor a minimal stop performance Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? A friend of mine installed it for me.
