When i come to a Complete stop, then I step on the gas, my vehicle starts to shake violently and the sounds are just horrible. I checked for all the signs for blown head gaskets and checked my tranny fluid. Nothing seemed out of the ordinary.It also has major power loss on take off. and forget about uphills; it goes about 5 miles an hour. It happens about 85% of the time.
Whats the violent shaking and sounds coming from my engine? on 1998 Kia Sephia

i would start with basics like plugs, coils and look for obvious vacuum lines broken or disconnected. if not, then you need a shop to help you out and give you a bid. Roy

One possibility can be the engine mounts are shot causing them to rumble against there metal housing. That can cause a poor engine performance and shaking. If the cars automatic, put on the parking brake hold down the brake pedal then put the car in gear and do slight acceleration either you or someone can visually look at the engine mounts when you accelerate to see how badly they move ... a good sign of failure would be that the engine looks like it wants to jump out of the engine bay.
