Idle speed is gone (Chevrolet Cruze J300)

To determine the causes of this malfunction, special diagnostic equipment is required, so in this case, contact a service station specializing in the repair of cars with fuel injection systems.



However, it should be noted that most often this malfunction is caused by a failure of the throttle position sensor installed in the throttle cover, contamination of the throttle itself, or the suction of foreign air through loose hose connections attached to the intake pipe. If cleaning the throttle valve or tightening the hose clamps does not restore idle speed, contact specialists to replace the throttle position sensor or replace the throttle assembly as a whole (see "Removal and installation the throttle assembly").
