Every time I start up my car it acts like it does'nt want to start. I have to try twice to get it to start and have to be pressing the gas. When the car is started, it makes a loud rattling noises and shakes continuosly in parked or with the foot on the brakes. It only stops when the car is moving. Could it be the catalytic converter?
