help!! got MILS and predator and still o2 malfunction

[HectorCobra03]

resently the SES light came on and dindt know why mi car had the MILS for a few months now few day back installed the predator and turn off the rear o2 sensors and still the SES came on and wen i go the trobble codes section of the predator it finds nothing but the SES still on .

went to the mecanic and he instals his obd2 tool and tells me that theres a o2 malfuntion

could it be a exaust leak? ive looked under the car and i dont hear nothing out of the ordinary

could i disconnect the rear sensors and put them off with the predator?


apreciate any info and opinions

thanks

the predator dosent show me any code ,a mecanic that ownes a 03 used his ob2 scaner and told me that it was a o2 code ,but i forgot to ask him the #

dang! i'm about to challenge an e55 for a rematch but i want the car to be at 100% before i do

just in case mi mods are:
upr xpipe
predator
2.80 pulley with 100mm idler
wm intake

your predator does show the number, well atleast mine does.
did you install your x pipe?
when i installed mine, i had a 4in harness between the o2 and the actual wiring harness. this gave me a o2 sensor circuit malfunction. i removed the harness and it went away.

try the predator again
