  • If you are experiencing idle surge, boost leaks, RPMs ramping up or down, or are unable to control your idle due to worn out gaskets, seals or BISS screw, you are in need of a throttle body rebuild. You may have to replace an electronic sensor such as the Throttle Position Sensor (TPS) or Idle Air Speed Controller (IAC / ISC), send in the sensors as well so we can test them!  Service prices do not include return shipping costs, that is calculated at checkout, returning UPS Ground to the customer.

Each throttle body rebuild consists of the following steps and new parts:

  • The throttle body is fully disassembled and degreased, soaked in solvents for a duration of time based on its condition.
  • The bare throttle body parts are then bead blasted using wet vapor blasting or dry glass bead media to prevent etching of the throttle body shaft or bore.
  • The bore is cleaned and inspected.
  • The shaft is cleaned and inspected.
  • New heavy-duty high-pressure shaft seals are installed.
  • New Base Idle Set Screw (BISS), BISS O-ring installed. (BISS caps obsolete for some models)
  • New Fast Idle Air Valve (FIAV) waffle gasket installed.
    • 1991+ only, 1990 DSM version obsolete
    • Some Montero FIAV gaskets available, some are obsolete depending on model/year
  • FIAV fully disassembled and degreased.
  • FIAV blockoff plate installed with new Hex-Cap high-capacity black-oxide finish Steel fasteners (optional upgrade for $40.00 for 1991-1999 DSM throttle bodies only).
  • FIAV bypass plate installed with new Hex-Cap high-capacity black-oxide finish Steel fasteners (optional upgrade for $40.00 for 1991-1999 DSM throttle bodies only).
  • New Idle Speed Controller (ISC) O-ring.
  • New ISC and TPS Sensor Fasteners.
