I had my mustang scaned at the autozone and it detected missfire in the first 100 rev and then the crankshaft sensor was bad, so i changed them and i changed the ignition coil but no luck do you think it's the throttle sensor or a blown head?

It could be your TPS. You can check it with a voltage meter. Turn your key on, and test the bottom wire. It should be around 1 volt, and go up when you turn the TB.

i've changed the TPS and the crankshaft position sensor and the plugs and the ignition coil and the wires and the car still has a bad vibration and it sounds loud do you think the catylic converters are burnout or the oxygen sensors are bad
