What causes Car Stalling in Traffic?
These are the faults we most often find behind this symptom on cars driven in Hyderabad's heat and stop-go traffic:
- Dirty or faulty idle air control (IAC) valve causing rough idle and stalling
- Low fuel pressure from weakening fuel pump
- Dirty throttle body with carbon deposits disrupting idle airflow
- Faulty mass airflow (MAF) sensor giving wrong air reading to ECU
- EGR valve stuck open, flooding intake with exhaust at idle

Frequently asked questions
Why does my car stall at red lights in Hyderabad traffic?
Stalling at idle is very common in Hyderabad due to stop-go traffic causing throttle body carbon buildup. When you stop at a signal, the throttle is fully closed — if the idle air control passage is clogged with carbon, the engine can't get enough air and dies. Throttle body cleaning (₹1,500–₹3,000) at Metre Per Second typically resolves this within 1 hour.
My car stalls more often in Hyderabad summer — is this related to heat?
Yes. In summer, the engine bay is hotter, causing fuel to partially vaporize in the lines (vapor lock) and the idle control valve to be more sensitive to carbon deposits. The ECM also runs a richer mixture, which can cause stalling if injectors are partially blocked. Metre Per Second recommends a throttle body clean + injector service combo for cars stalling in Hyderabad summer.
