I already cleaned the throttle body and replaced the IAC valve. I also checked for vaccum leaks but it still was rattling an shaking a lot to the point where I could see it but the car is not throwing any codes.

Usually it will throw a misfire code if it's that bad. Check fuel pressure then do compression test
