The engine has a notable shake around 1050 rpm. For example, upon starting the car, the rpm goes up and when the rpm moves down to 1050, the engine shakes. It holds there for a few seconds and goes down to idle (around 800rpm), and the engine stops shaking. The shaking is consistent while accelerating and decelerating. I have changed the spark plugs, wires, rotor and cap, air filter.

It still sounds like you may have a spark problem here, I would check both fuel and spark to see where we can narrow this down to. if you dont know how to check it I will send you some instructions, also I wanted to ask , is there a check engine light on?

Thank you.

I can definitely feel the car shaking. As far as seeing it, I THINK I can see the engine shaking. I don't really remember what the movement of the engine looked like before. The check engine light is not on.

i dont think its as serious as I initially thought, besides the fact that you may need a motor mount, I think a really good throttle body cleaning and Idle air control valve. that will clear you up.

Thank you. I'll try the cleaning and then look at the IAC. Will let you know what I discover.

If it is the motor mount, is there a danger if I continue to drive the car?

not really, however, you may start to put strain on the others causing pre mature wear, or in one case that I had, the refrigerant pipe ended up cracking because there was so much movement that it put too much strain on the pipe and it gave way.. but the engine isnt gonna fall out or anything serious like that
