When the car reaches 50 mph it starts to shake and the check engine like blinks on and off and when you reach 60 to 65 mph it smooth off. But when it drop back down to 50 it starts the shake all over again.

What I need you to do is take the car to a nationally recognized parts store and have them scan the computer for codes. IF the engine light comes on, there will be a code/s stored in the computer that will point us in the right direction.

Have that done and let me know what you find. Ask them for the code numbers so I can review them. Don't purchase any parts until I see the codes.
