Have autozone reset them or pull your neg battery termainal off and let it sit for a bit and then reconnect, what codes was is throwing? If they keep coming back then the issue is probly still there.

PCM Reset

Turn key on, don't start car
Pull PCM BATT and PCM IGN fuses in engine compartment
Wait 5-10 min
Turn ignition off
Replace fuses

This will clear all current and history codes, along with the readiness tests, stored idle, etc. Idle will be grumpy until it relearns.
