Either remove fuse F2 in the passenger compartment fuse box or the negative battery cable for 10-15 minutes.

Either will clear the keep-alive memory and will restore all the data tables to defaults.

If your PCM was re-programmed by a tuner or a similar device, that is a different matter.
If your original owner's manual is missing, download a soft copy from under the PARTS AND SERVICE tab.
