Throttle Body Overhaul: Disassembly

Throttle valve screws are staked in position and should not be removed. Before working on throttle body assembly, it is essential that residual pressure be relieved before throttle body is removed. See FUEL PRESSURE RELIEF under FUEL SYSTEM (TBI) in this article.

Pressure regulator includes spring under heavy tension which may cause personal injury if released. DO NOT
immerse cover in any type of cleaning solvent.
