This morning I've noticed a very unusual problem with the engine. When I start the car, the engine shakes as it it's kinda thrown from side to side. Also, I feel as though the acceleration was awkwardly slow. I was supposed to go to school today, but afraid I might damage the car even worst. I was wondering what seems to be the problem?

BTW, it's a unmodified stock KA24DE engine.

 

okay...I've just cleaned out the air filter. Do you think that's the problem?

 

Loose mounts?

 

Could be mounts, could be timing(could be off).

 

Loose spark plug wires can also cause that.
