Throttle Body
Removal and Installation
Tools Needed:
8mm Socket (Throttle Cable Assembly)
10mm Socket (Negative Battery Cable)
13mm Socket (TB hold-down bolts)
#25 Torx driver (TB sensors)
3/16” Allen wrench (New TB hold-down bolts)
1)
Remove the Throttle Body hat. If you already have an after market air intake
(Quick D, Intense
Performance, Mopar®, K&N®, etc.), it
will be much easier, if not, just remove the flex hose and the
Throttle Body hat.

2) Now there are three electronic
connections attached to the TB. There is one in the rear, and two
on the driver side. The ones on the side are
the push and pull type. Push down on the tab, and pull
it off. The one on the rear is the pry type.
You need to lift the tab a bit to be able to slip it off. You
may also now remove the vacuum line from the
front of the TB.

3) With the electric connections removed,
it's time to move to the Throttle cables. There are three
cables attached to the TB. Do not try to pry
them off. They are held on by kind of a "C" connection.
The little black parts at the end of the
cables attach to the TB by being pushed on, and they are
removed by being pushed on in the opposite
direction. The "C" looks like this…C-------- you have to
push it past the stud. You will understand
once you see it. They are C clips with the cable attached.

from throttle pedal and cruise control. |

4) Now if you have gotten this far... You are
home free. There are three 8-mm bolts holding the
Throttle cable attachment brace to the TB.
There are two bolts in the front, and one just behind the
spring on the side. The brace will still be
attached to the cables so don't try to move it very far; we
just
wanted to release it from the TB housing. (KEEP THESE bolts, as you will need
them for Step
#8)

5) With the brace loose from the TB it's
time to remove the four bolts on top of the TB. Once they
are removed, you will be able to lift the TB
off of the Intake plenum. Once it is removed, make sure
you cover the opening with a towel, or
something, to make sure nothing falls into the opening.

6) Now away from the engine, preferable on a
bench, you can safely remove all the sensors and
install them on the Fastman TB. The one in
the back is the Idle Motor, the one on the driver side is
the Throttle Position sensor, and the one in
front is the MAP sensor. You will need a #25 torx
wrench; it is the little star looking
driver.

7) Remove any gasket material from the
intake plenum. Put down the new gasket included with the
kit (please do not use any RTV). I have
included a new S bolt, and 4 new button head bolts to use
instead of the stock bolts.
8) Place the Fastman TB on the gasket and
start the bolts into the plenum. It is easier to start all 4
bolts first then go back and tighten them
down (remember the intake plenum is aluminum, so DO
NOT over tighten). Then attach the cable
support brace using the stock 8-mm bolts you removed in
Step #4 and reattach the cables, and the
electronic connections.
9) The final step is to install the S bolt.
Thread it until the double nuts hit the TB. If it is not aligned
to the rear of the TB, then you will have to
loosen the bolts and turn it either counter or clockwise
until it is properly aligned…then tighten it
down.
10) Then replace the TB hat, and anything
else you removed.
11) The next step is to disconnect the
negative side of the battery for a 10 to 20 seconds, this will
reset the computer and allow it to relearn
the setting with the new air flow rates. It should reset in
about 40 miles. It may run rich for the
first couple of minutes. Don't worry, it will relearn the proper
settings.
12) The last and most important step is to
put your Stock TB (and old S bolt if you already had the
Quick D intake kit) in the box and return it
ASAP. I will return your voided deposit check upon the
receipt of the core.
