What are the symptoms of a faulty throttle in the Cruze?
2 Answers
Cruze throttle failure symptoms refer to phenomena such as the car failing to start, emitting black smoke, and high fuel consumption. Below are the relevant details: Car fails to start: Unstable engine idle, persistently high idle speed that does not drop, difficulty starting the engine, especially during cold starts. The engine idle is unstable or there is no idle. When using a fault diagnostic tool to check the throttle, observe the data stream. If the throttle opening is large, cleaning is necessary. Generally, replacement is not required if there are no permanent fault codes. Emitting black smoke and high fuel consumption: Excessive carbon buildup can cause the EPC light to frequently illuminate, the vehicle to suddenly stall while driving, and continuous shaking. Remove the throttle, perform a thorough cleaning, and then re-match it to resolve the issue.
Driving my Chevrolet Cruze with a faulty throttle was really frustrating. I remember the car shaking violently right after starting, and suddenly stalling at a red light, almost causing a traffic jam. Stepping on the accelerator had no response, and the fuel consumption skyrocketed from 9 liters to over 12 liters, with the check engine light constantly lit on the dashboard. After inspection at the repair shop, it was found that the throttle was completely clogged with carbon, affecting the air intake balance. The mechanic cleaned it, and the problem disappeared, but the lingering sense of insecurity from before remains. I recommend cleaning the throttle every two years to avoid similar troubles. With cars, regular maintenance saves worry, money, and even lives.
