| Vehicle Speed Control problems |
The engine lights come on, then the car starts chugging and shuddering and sounds and feels as if it will shit down. I am not able to accelerate. This is a serious safety risk in traffic, especially if driving on the interstate. The car will not move at anything over 20 mph, if it even accelerates at all. I usually end up coasting to the side of the road and shutting the engine down. I let it sit and turn it back on and it may or may not let me go again.
