Frequently asked questions
Why does my car shake and vibrate at idle in Hyderabad stop-and-go traffic?
Rough idle in Hyderabad is almost always caused by throttle body carbon buildup from city stop-go driving, or spark plug fouling from rich fuel mixtures in traffic. When your car runs at idle in traffic for long periods, the low-velocity airflow allows carbon to deposit on the throttle plate and bore. Throttle body cleaning (₹1,500–₹3,000) at Metre Per Second typically resolves rough idle within 1–2 hours.
