IMPORTANT: Never mix up throttle bodies of nor-
mally-aspirated and supercharged 4-TEC engines.
Doing so will automatically lead to a misfunction of
the EMS and will cause a bad engine calibration.

Mechanical Inspection
Check that the throttle plate moves freely and
smoothly when depressing throttle lever. Take this
opportunity to lubricate the throttle cable.
IMPORTANT: The throttle body is designed to be
tamper proof. Changing the idle stop or modifying it
in any way will not increase performance or change
the idle speed but may cause poor startability and
erratic idling.
Before replacing any part, check the following as
these could be causing the fault. Perform the test
while the engine is not running.
– Throttle cable adjustment too tight. Not return-
ing fully to idle stop.
– Throttle body idle set screw is loose or worn.
– TPS is loose.
– Idle bypass valve is loose.
– Corroded or damaged wiring or connectors.
– Throttle body has been replaced and the Closed
Throttle and Idle Actuator reset has not been
performed.
