throttle body troubles
Did a tune-up to my 06 mustang gt. Also decided to take off throttle body and clean it. After reinstalling it there seems to be a lag on throttle responses on deceleration. Not sure if throttle body cleaner got into springs on side and caused slow response to return to idle or what. What can I do to cause it to return to normal. Thanks, Scott Roberts

Stock tune? There is a delay so as to burn all the fuel vs an immediate throttle close which would put unburned fuel into the atmosphere. Many after market tunes dial this out so there is a more immediate throttle close.
Also, assuming you disconnected the battery before cleaning the throttle body, you have to do both of these steps afterwards. If you didn't disconnect it, do it anyway. Some say for a half hour, some say for a few hours. Mine was disconnected for several hours.
Throttle recalibration:
1.Turn on car without starting the engine
2. Wait til the dashlights stabilize (some of them will turn off)
3. Step on the gas pedal in one smooth and steady motion
4. Once gas pedal hits the bottom, let go
5. Turn off car and wait 4-5 seconds
6. Turn engine on
7. Drive
8. Repeat 1-6 if it doesn't work the first time.
Idle re-learn:
Start the car and let idle for 8 minutes without touching the throttle at all.
Now put the A/C on for 2minutes, still at idle without touching the throttle at all and without shutting of the car.
Now after 10 minutes of idling (8 without AC and 2 with AC), you can drive the car for approximately 10 miles... make sure it's not just highway, but stop signs, traffics lights, etc. You will have completed the idle learning process.
