Q: Car stops accelerating and check engine light comes on momentarily while driving.
On occasion while driving my car the theft light, check engine light, and battery light turn on and the speedometer will drastically drop for a second. It also feels like my car stops accelerating when this happens. This can happen when driving on the freeway or driving in town. Power relay maybe? Any advice?
My car has 180000 miles.
My car has an automatic transmission.
