Midsize LTD L4-140 2.3L SOHC (1986)
Idle Speed/Throttle Actuator - Mechanical: Testing and Inspection
Throttle Solenoid Positioner With Dashpot
With the throttle open and the solenoid electrically energized, the plunger should extend.
Push the dashpot plunger in to the collapsed position, and if no resistance is felt or if excessive force is required to bottom the plunger, the dashpot is
defective.
If either component fails, replace the assembly.
