What do I do?
Camaro 99', Headers, dynacat (catalyc)
Code: Catalyst efficiency low-bank 1
This is the only code I got. Since I fixed the EGR leak, I'm doing 21 or 22 mpg HWY/city. Before that, 17 mpg. I planning to tune the PCM and the AFR. What do I do first? To get a new catalytic or to get a O2 wideband? I'm new in this tunning and AFR stuff. What the best thing to do to get performance and not to run rich or lean?
