I was wondering if anyone has had any issues after running a Diablo Tuner on their car? I turned the DOD off. After driving awhile I got the messages "service traction contol", "service stability" and I'm getting the code P0121. I know the code is for a TPS but the cars are drive by wire, so which sensor is going bad? The throttle body actuator or the pedal position sensor? This morning she was sitting at a traffic light and almost died till she tapped on the gas and it stayed running. It's happened a few other times as well. Any help would be great. Thanks
