Mercedes GT Roadster Engine Power Loss

I also own a GT Roadster and had similar problems The symptoms you describe, particularly the reduced power and rough running, point to a potential fuel delivery issue The mass air flow sensor could be a culprit, as it regulates the air entering the engine An incorrect reading from this sensor can throw off the fuel mixture However, it could also be the fuel injectors themselves Have you noticed any changes in your fuel economy

Thank you for your reply Regarding fuel economy, I believe it has decreased slightly What exactly does the mass air flow sensor do, and if it's faulty, is there a way to test it And if it's the fuel injectors, is that a difficult repair

The mass air flow sensor measures the amount of air entering the engine This information is crucial for the car's computer to determine the correct amount of fuel to inject A defective sensor can cause the engine to run lean As for testing, specialized tools exist, but diagnosis is best left to a qualified technician Given the symptoms and the potential complexity, I would recommend taking your car to a trusted workshop They will be able to accurately diagnose the problem and perform any necessary repairs It's a better approach than potentially causing further damage

I appreciate the advice I took the car to a shop, and you were right – it was a defective fuel injector They replaced it, and the engine is running smoothly again The total repair cost was approximately 515€ Thank you again for your insights
