HELP! O2 Simulator I gutted my cats and the (service engine soon) light came on. I bought O2 simulators and installed them tody. I unhooked the battery for about a minute and hooked it back up and started the car and the (service engine soon) light still came on. Does it take a while for the light to turn off?
reset your PCM by turning the key to the ON position and removing the PCM BAT and PCM IGN fuses under your hood. These are located on the driver's side in two seperate boxes. Unplug them and wait a few minutes to put them back in. If the SES light still comes on that your car might have another problem.

Do as above, disconnecting the battery for a short period may not be enough to clear the PCM , but the fuse method will do it...
you are replacing the rear O2s with the sensors right? (stupid question but just to cancel out all variables)
