ok the sotyr is i put on a meganafloe high flow cat converter last week now all of a sudden my engine lights comes on i hook up the scanner and its telling me my 02 sensor on the manifold is acting up how can i fix this problem besides getting a new sensor caus ei dont think that is causeing the problem

 

whats the code?

 

do you have a spacer on it?

 

o man i dont member off the top of my head one is sensor one bank one and the other is something like 02 bank one switching signals something along the lines of that

 

bumppp

 

What is the exact code? Alot of the time if you put on a high flow cat you will get a code for cat efficiency. Only way to remove that CEL is to tune it out or put a spacer on the O2 sensor.
