i just done my na-t last week, after i drove 30 miles the CEL came on, i don't have cats on my car, so i think maybe that is the reason of the CEL. i wired 2 front o2 sensors to one and installed it right after the turbo in my downpipe also installed the bottom o2 sensor on the other side of the downpipe.
my car is a 1992, if there is not cat installed on the car which o2 simulator will throw a CEL?
will o2 simulator will take away the CEL, if so which one should i replace with the simulator?

The rear O2 sensor is the one that detects if you cat is functioning properly. You may need to get an O2 simulator.

Its actually more like a little box. instead of plugging your engine harness into the o2 sensor, you plug it into the simulator.
