I cut r2 and r3 for analog input 2 to be used. for a fuel pressure sensor.
and also cut. r136 and r 138 for my wideband
Now when i go to start the car. its getting cel code 9 cyc 1 sensor.

cutting those resistors out shouldnt have messed up the ecu though right?
and i am afraid to cut them out if i get a new ecu cause i dont want the exact thing to happen.

Those resistors will have nothing to do with that error. Try your s300 in a different ECU.
