What causes Engine Hesitation on Acceleration?
These are the faults we most often find behind this symptom on cars driven in Hyderabad's heat and stop-go traffic:
- Dirty throttle body causing slow throttle response at initial opening
- Faulty throttle position sensor — ECU doesn't respond fast enough to pedal input
- Dirty fuel injectors — fuel delivery delay under rapid throttle opening
- Accelerator pump failure (carbureted cars) — momentary lean surge on opening
- Spark plug misfire under transient load — stumble when picking up speed

Frequently asked questions
My car stumbles when I first press the accelerator in Hyderabad traffic — what causes this?
A stumble or hesitation at initial throttle opening is almost always a dirty throttle body or TPS sensor fault. In Hyderabad's stop-go traffic, the throttle is opened and closed frequently — carbon deposits on the throttle plate create resistance to initial opening, causing a brief lean stumble. Throttle body cleaning (₹1,500–₹3,000) at Metre Per Second resolves this in 90 minutes. If the stumble appears after cleaning, the TPS sensor needs replacement.
