P0430 Catalyst System Efficiency Below Threshold (Bank 2)........ WHAT THE HELL DOES THIS MEAN??? my car is like stuttering when in lower RPMs when u step on it

 

Youre exhaust system (catalytic convertors in specific) is probably messed up. Get the piping and durability checked out by a muffler shop, then go to an auto care specialist to take a look at your computer and stuff...

 

Hey Stone. I work for a dealership, its way too late right now. But i'll look into it for you tmrw after i wake up.

 

thanks alot casper, about the catalytics though, i dont have any, but i just replaced a 02 sensor that was working and since then this code has popped up
