Thankfully, she was able to coast down the bridge and pull into an empty parking lot. This was extremely dangerous because the vehicle lost power while being driven and could have caused a serious accident. After turning the vehicle off…

While driving, the vehicle hesitates and stumbles during acceleration, is slow to build RPM, and fuel economy has noticeably decreased. During one hard acceleration event, the vehicle lost power and…
