Filed Oct 21, 2020 · Acceleration · 138,000 miles · TX

I was driving on the highway going 50mph and the car stalled and went down to 20mph and it shut off. I was able to get it started again and was only able to go 20mph all the way home. My car insurance app has engine alerts and it stated it is the throttle/pedal position sensor/switch 'd'/'e' voltage correlation. The the alert stated it was urgent because it decreases the engine performance and the engine may enter limp home mode. I was very lucky no cars where behind me when this happened.
