Basic Throttle Body Installation Instructions

Replacing the original throttle body and installing an Accufab throttle body is considered a “bolt-on” modification.  In most cases it is an “off with the old and on with the new” process.  In some cases, some minor modifications are required.  If, for instance, the new throttle body is larger than the inlet hole in the intake manifold, some minor grinding or chamfering of the inlet hole may be required.  On the 1996-1998 Cobra installations, the bridge between the dual-hole intake manifold must be ground or cut out so as to permit the installation of the larger single blade Accufab throttle body.  All of these tasks are relatively easy to do, however, if any part of a throttle body installation is thought of as being difficult, or if you are uncomfortable with doing it yourself, we recommend getting advice or consultation from a professional. 

 In general, here are some generic throttle body installation instructions.  Disconnect the ground cable from your battery.  Remove the Throttle Position Sensor (TPS) from the original throttle body.  If the original throttle body also has an Idle Air Control motor (IAC), remove that too. 

Remove the original throttle body (typically, four bolts).  If the vehicle requires any modifications to the intake manifold, do that now.  When that is complete, install the new Accufab throttle body.  Then, re-install the IAC and TPS.  

Reconnect the battery cable. 

Adjusting the TPS to the correct voltage is not difficult.  Refer to the article regarding TPS Adjustments in this Tech Section.
