OK, I am pretty sure I broke my catalytic converter. How is not important, suffice to say it involved a curb that I did not see
Anyway, when I started up this morning I heard rattling (like a rock in a can) and it seemed to emanate from the center of the car. I'm going to jack it up tomorrow to verify.
What I have also noticed is that the car has lost power. I can cruise at 75 without issue but it seems it take far longer to get there and pressing the go pedal does not seem to be very effective at making it happen as quick as it used too.
Also, when the engine is under load (even slight pressure of the gas pedal) I hear what sounds like a faint high pitched whistle. The second I let off the gas it stops and under even cruise it is not present. It only manifests it's self under acceleration.
Could a broken cat do this? Am I looking at more than just a busted cat?
TIA for any input.
