ما الذي يسبب اهتزاز المحرك أثناء التوقف في الإمارات؟

The most common cause of engine shaking while stationary in the UAE is misfiring spark plugs, often worsened by local high temperatures and fuel quality considerations. A single misfiring cylinder in popular GCC-spec models like the Toyota Camry or Nissan Sunny can create a very noticeable vibration, especially when the air conditioning compressor kicks in during a 45°C Dubai summer. For a typical 4-cylinder sedan, the repair cost at an independent garage in Sharjah Industrial Area for replacing all four spark plugs and ignition coils ranges from 600 to 1,200 AED, depending on the brand of parts. The second most frequent cause is degraded engine mounts, which are stressed by constant stop-and-go traffic on Sheikh Zayed Road and the heavier weight of vehicles often running at full A/C load. A visual and pry-bar inspection by a mechanic can confirm this. Preventive maintenance is key: follow the severe use schedule in your owner's manual (more frequent than normal conditions) due to our climate and traffic. RTA Dubai's vehicle inspection data consistently lists engine misfires and excessive vibration as common reasons for initial test failure. Meanwhile, a 2023 report by the UAE's Ministry of Industry and Advanced Technology (MoIAT), referencing GSO standards, emphasizes the importance of using the correct fuel grade (like Special 95 or Super 98) as specified for your GCC-model engine to ensure optimal combustion and prevent carbon buildup that leads to shaking.

As a used-car showroom manager in Dubai, the first thing I check when a customer complains about a shaking engine in a car they just bought from elsewhere is the engine mounts and spark plugs. For GCC-spec cars that have seen desert use, the mounts can get brittle faster. A quick test is to have someone shift from Drive to Reverse while lightly pressing the brake – if the shake gets worse, it’s likely the mounts. We see this a lot on older Nissan Patrols and Toyota Land Cruisers that have been off-road.

My 2018 Hyundai Tucson started shaking at traffic lights near Ibn Battuta Mall last summer. The check engine light was flashing. My mechanic in Al Quoz found that two ignition coils had failed, probably due to the extreme heat under the hood. He replaced all four coils and the spark plugs for about 900 AED. He also advised me to always use Special 95 fuel from reputable stations, as lower-quality fuel can leave more deposits. The shaking disappeared completely, and my fuel economy on my daily Dubai-Sharjah commute improved slightly.

Don't ignore a shaking steering wheel when parked. It often starts small. For UAE taxis or ride-hailing cars with very high mileage, this is a frequent issue. Beyond spark plugs, get your fuel injectors checked for clogging. A professional fuel system cleaning service costs around 400-700 AED and can solve the problem if it's carbon-related.

From a fleet manager's perspective, consistent vehicle maintenance is cheaper than major repairs. For our company's fleet of Toyota Hilux and Ford Territory vehicles operating between Dubai and Abu Dhabi, we enforce spark plug changes every 60,000 km, not the recommended 100,000 km. Our desert driving and heavy idling in traffic justify the shorter interval. This proactive practice, based on our own cost-per-km calculations, has virtually eliminated roadside complaints about engine shaking and has improved our vehicles' first-time pass rate at RTA testing centers.
