Help T.B. needs replaced
Hi everyone....anyone out there who can give me details of replacing the throttle body on my 2005 Mustang GT. Replacing it with 05 Stock one. I do have a tuner XCal. II, but not sure if I need it for this or not. I'm clueless here, I have already purchased it, just have to have someone install now, and before I do that, I want to make sure they would be doing it right
Sooooo any help would be appreciated
ps: I've already spent $$$ on car, and can't anymore right now, so a friend will install, but I'm not sure he knows all the details.........so please please please any help.....

Why are you replacing the TB on your car with a stock one? Your post is confusing.
Anyway, a TB replacement is very straight forward. You need to disconnect the intake tube from it, remove the bolts that hold it in and pull it out. I have never done one on an 05+, but it should take you less then 30 minutes unless something gets hund up.
BTW, since you sound like a Noobe, here are some things to keep in mind.
1 - Don't drive or even run the car unless everything is hooked back up.
2 - Don't drop anything inside the intake while components are removed.
3 - While this is a very easy swap, cars will sometimes idle or even run poorly after a TB swap and the TB may require some adjustment.
Replacing the TB on an otherwise stock car is pretty pointless and there are probably much better ways to spend your money and your time (but hey, we have all been guilty of this). The risk vs return just ain't there if you ask me.

1. Loosen the hose clamp securing the factory molded intake hose to the factory throttle body.
2. Remove the intake hose from the throttle body.
3. Disconnect the electrical connectors from the TPS sensor and the throttle motor.
4. Loosen and remove the (2) bolts and (2) nuts securing the throttle body to the intake manifold.
5. Make sure that the factory rubber o-ring style gasket remains in the intake manifold. If it falls out simply put it back in.
6. Take the factory throttle body and place on a flat surface and remove the TPS sensor which is located on the passenger side of the throttle body.
7. Install the TPS sensor onto the GMS Billet Throttle Body. Make sure to orientate the sensor in the same direction as it was when installed on the factory throttle body.
8. Remove the (5) screws securing the gear cover and throttle motor to the factory throttle body. Do not remove the (2) Phillips head screws that secures the motor cover.
9. Carefully separate the gear cover from the throttle body by slowly lifting the cover away from the throttle body. You will notice that an internal spring is still engaged. By carefully tilting the gear cover/motor assembly at a slight angle rotate the assembly clock-wise until the spring pressure is released and the spring tang is also released from the inner gear. Lift the cover/motor assembly fully away from the throttle body and set aside. If the throttle return spring releases and falls out once the pressure is relieved, this is okay.
10. If the throttle return spring with plastic locking cap became separated from the gear cover during the previous step it must now be re-inserted into position in the gear cover.
11. Looking down onto the cap, notice the (2) different width locking tangs. Position these tangs into the corresponding slots of the throttle return spring pocket in the gear cover. Apply pressure in a slight counter-clockwise rotation to lock the tangs into position.
12. Carefully position the gear cover with throttle return spring over the throttle body throttle shaft. Align the throttle return spring so that the metal tang aligns with the hole in the recessed area of the throttle shaft gear. Be sure to engage the metal spring tang into the hole through the gear.
Note: If the gear cover assembly has a cap over the throttle return spring follow steps A - D Skip step 13 and 14
A. Use a small screw driver the pry open the lid at the latch
B. Replace the cover on the throttle body, once aligned press both assemblies together and secure with the (5) screws originally removed in step 8
C. Using a screw dirver, Apply pressure in a slight counter-clockwise approximate ¾ of a revolution to lock the tangs into position
D. Replace the spring cover.
Skip step 13 and 14
13. Gently rotate the gear cover assembly in a counter-clockwise rotation approximate ¾ of a revolution until the cover realigns with the throttle body. Note:This step can be accomplished much easier if the throttle return spring is stretched in length approx. ¼ inch longer than stock. This will allow both sets of tangs to stay engaged while rotating.
14. Once aligned press both assemblies together and secure with the (5) screws originally removed in step 8. Rotate the throttle shaft throughout its full range of motion by moving the throttle blades with your finger. Check that there are no areas of bind and that the movement is smooth.
15. Place your GMS Billet Throttle Body up to the intake manifold and secure with the original hardware. Do not over tighten as you may pull the threaded inserts from the composite manifold.
16. Re-attach the intake hose to the throttle body and tighten the hose clamp.
17. Reconnect the electrical connectors to the TPS sensor and the throttle motor.
18. Start engine and make sure idle is normal. Depress accelerator and check for smooth feel and operation.
19. Close hood and have fun!

TBS?? Not sure what that is. BTW - No Newbie, But Female I've been told the spring inside the TB is wacked. I bought a Granatelli TB, had someone put it on, and it would NOT work what so ever, so the original TB was put back on. Car goes in Fail Safe Mode alllll the time. Dealer says T.B needs replaced, plus I took it and had it re-tuned, I have a JLC cold air intake, and of course had to purchase the XCal tuner for that, but spent 450.00 to see if that would correct problem, and it didn't........So now it's New TB time
