If you have a idle issue or what you may think is an ecm issue this procedure would be the first step as it is quick and many times it will address a issue with idling erratic or not starting. This will also clear a diagnostic code that popped up due to disconnecting your O2 sensors or if any sensor errored out the following method will clear those as well.
Perform the following steps EXACTLY to reboot the ECU.
(1) Turn off the ignition if on.
(2) Turn the ignition on/off for 5 cycles within 5 seconds.
(3) Turn off the ignition for 15 seconds.
(4) If on restart the code returns then it is a active code and you need to hook up some diagnostics to it.
