Once idle it steadily shakes and makes a lot of noise. Once above 65 starts riding more and more rough like as if I'm pushing the car too hard
My car has 127000 miles.
My car has an automatic transmission.
The rough idle may be caused by a variety of things, but this happens most commonly when the mass air flow sensor or the idle air control module have failed. The mass air flow sensor is responsible for monitoring the air intake as it is mixed with the fuel just before being injected into the motor. When this is not functioning properly, this will cause an imbalance in the air-to-fuel ratio which will cause the rough idle and ride as you describe. I would suggest having an expert from YourMechanic come to your home to diagnose and repair this.
