MAINTENANCE
Throttle System
Throttle Freeplay
If the throttle pedal has excessive
play due to cable stretch or mis-
adjustment, it will cause a delay
in throttle response, especially at
low engine speed. The throttle
may also not open fully. If the
throttle pedal has no freeplay, the
throttle may be hard to control,
and the idle speed may be erratic.
Check the throttle pedal freeplay
at the intervals outlined in the
Periodic Maintenance Chart
beginning on page 52. Adjust the
freeplay if necessary.
Throttle Freeplay Inspection
1. Engage the park brake. Shift the transmission to neutral.
2. Apply the brakes. Start the engine. Allow it to warm up thoroughly.
3. Measure the distance the throttle pedal moves before the engine
begins to pick up speed. Freeplay should be 1/16 to 1/8 inches (1.6-
3.2 mm).
WARNING
Failure to check or maintain proper operation of the throttle system can result
in an accident and lead to serious injury or death if the throttle pedal sticks
during operation.
Always check the pedal for free movement and return before starting the
engine and occasionally during operation. Never start or operate this vehicle
if it has a sticking or improperly operating throttle pedal. Immediately contact
your dealer for service if throttle problems arise.
