As I am cruising between 55-60 mph in my '95 neon, it'll tug back and forth as if it wants to stop running. This tugging back and forth is kinda scary as I'm not sure if I would lose power on the expressway. I also noticed that my engine light comes on and off during this tugging process. Also, as I am pulling into park, the engine will die but I have no problem starting up again. This also happens if I am slowly turning. Any advice would be appreciated.
