cobalt ss lnf codes help
 
hello I have chevy cobalt ss turbo and I have these relative codes O2 Sensor P0030, P0031, P0036 and P0037 the car worked well, the problem came after finishing installing the new clutch, the sensors are new and I changed them and the problem continues. What can be something wrong connected, a fuse, tune, bad pcm?Thanks for any help

id double check the plugs on the bottom of the fuse box. actually pull the plugs back off and inspect the pins. all 4 codes are o2 heater circuits, the power for the o2 sensors comes directly from the fuse block.
