The Mercedes-AMG GT uses a 4.0 M177 V8 biturbo (476–630 bhp variants) and is classified as a sports. Based on our workshop experience with Mercedes-AMG GT in Hyderabad: M177 timing chain kit service at 60,000 km under AMG driving loads. We also see rough idle in vehicles that share similar engine architecture to the Mercedes-AMG GT.
Throttle body cleaning at every 40,000 km service prevents the most common rough idle cause.
What causes rough idle on petrol cars?
The most common cause is a dirty throttle body — carbon buildup causes irregular airflow at idle. GarageNation cleans throttle bodies with chemical spray as part of major service (included). If cleaning doesn't fix it, the next steps are spark plug inspection (₹3,500–₹8,000 for a full set), ignition coil test, and intake leak test.
