bad cat question

[blklscmd]

Today i was driving around and as soon as i hit the accelerator i hear a marble rattling sound.Is this a sign of a bad cat?It wasnt driving as good as it usaually does.It also cut off on me at the light.Does anyone know a way i can test it?

yes....bang on the cats with your hands and see if they rattle

Maybe you are running rich?

 

[blklscmd]

why would one run rich?

 

[Frogman]

Because one shouldn't run lean... Which I think is what Abbens meant.
