First off make sure that your Back up fuse under the hood is not blown, 7.5 amp. It shouldn't be as your clock would reset everytime you cycled the key. Then you need to check your O2 sensor curcuit to make sure that it is operating correctly. That is if you still have a 1 blink code.
That will be 65 dollars, unless you want this ***KER after you!!LOL
