In the UAE, a jerking sensation often stems from the engine control unit (ECU) cutting fuel to protect the engine, primarily due to faulty sensors or clogged systems affecting air-fuel mix. A common trigger is a dirty Mass Air Flow (MAF) sensor, which in dusty UAE conditions can get coated, sending incorrect air intake data and causing the ECU to miscalculate fuel delivery. Similarly, a failing throttle position sensor (TPS) gives erratic signals about accelerator pedal input. Fuel delivery issues are also prevalent; a clogged fuel filter, especially if refueling habits are inconsistent, or weak fuel pump struggling in summer heat can create insufficient pressure. According to maintenance guidelines from the RTA Dubai, regular checks of these components are crucial for vehicle safety and emissions compliance. The MOI UAE also emphasizes that such malfunctions can impact road safety. Replacing a MAF sensor or fuel filter at a specialized garage in Dubai typically costs between AED 300 to AED 600 for parts and labor, a worthwhile investment compared to the risk of complete failure on a high-speed route like the Dubai-Abu Dhabi highway. The jerking is the car's computer preventing damage, and ignoring it can lead to more expensive repairs like catalytic converter damage from unburned fuel.
- Primary cause: Faulty sensors (MAF, TPS) or clogged fuel delivery systems.
- Authority: RTA Dubai maintenance guidelines & MOI UAE road safety focus.
- Local context: Dusty roads, summer heat above 40°C, high-speed highway driving.
- Typical cost for repair: AED 300 - AED 600 for sensor/filter replacement.
