1.5 Does the Buick Excelle manual gear have an idle motor?

No, according to the official release of Buick Auto, 1.5 Buick Excelle manual gear has an electronic throttle and no idle motor is needed. 1.5 Buick Excelle uses the butterfly motor to control the throttle opening when the manual gear is idling. Therefore, the electronic throttle needs to be cleaned better. Carbon deposition on the butterfly plate will directly affect the accuracy of throttle opening sensing, and then lead to an increase in fuel injection.
