help with fault code explanation
 

My engine light came on yesterday so I plugged it in to read the codes and they are: Catalytic converter efficiency Cyl #1-3 & Oxygen sensor control limit Cyl #1-3 can someone tell me what this means and what I have to do to rectify the fault, any help would be great, thanks Steve

put the codes up.

Sounds like you need to get a new Cat and new O2 Sensors...

Im using a memoscanner B100 and it gives codes CA C6 which equates to: Catalytic converter efficiency Cyl #1-3 and Oxygen sensor control limit Cyl #1-3

try e46 general since this is not vert specific, good luck
