i have not touched the first o2 sensor only the 2nd one
If you removed both cats, you are in a world of hurt. As far as I know, there is no way to avoid a CEL with the first CAT Gone. The second O2 sensor is checking that the CAT is working. You may be able to replace the O2 sensor with a circuit that fakes the ECU into thinking the gas has the right mixture, but no spark plug adapter is going to do it.
