First find out what code your throwing. Did you mess with the throttle body at all? If it's a P0507. Try doing the Idle Air Volume Relearn.

1. Perform "Accelerator Pedal Released Position Learning".
2. Perform "Throttle Valve Closed Learning Position".
3. Start engine and warm it up to normal operating tempurature.
4. Make sure all prep items are completed before moving on.
5. Turn ignition "OFF" and wait at least 10 seconds.
6. Confirm that accelerator pedal is fully released, turn ignition switch "ON" and wait 3 seconds.
7. Depress and release the accelerator pedal 5 times within the next 5 seconds.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approximately 20 seconds until the "SERVICE ENGINE SOON" light stops blinking and turns on.
9. Fully release the accelerator pedal within 3 seconds after the SES light goes off.
10. Start engine and let idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure that idle speed is within specifications. (700+/-50 RPM unless you had it altered.)
13. If idle still doesn't work right, curse and spit because you gotta start over. Check the following 3 before starting over: throttle body is closed when the vehicle is off, PCV works in stock form, and no intake manifold leaks

If the battery was disconected for over an hour Idle air volume relearn has to be performed
