Why does the car suddenly lose power when accelerating on the highway?
1 Answers
The sudden loss of power when accelerating on the highway is due to issues with the fuel system. Areas to inspect: Fuel injectors, fuel pressure gauge, and air filter. Effects of different fault locations: Clogged fuel injectors can affect fuel delivery; non-standard fuel pressure, typically low pressure, insufficient fuel pump delivery, damaged fuel pressure regulator, blockages, fuel filter issues, or overly lean air-fuel mixture can all cause acceleration weakness. Additionally, a clogged air filter, leaks in the intake system, or failure of sensors controlling fuel injection can also lead to poor acceleration. Over time, this can affect the fuel filter and fuel lines, causing poor fuel delivery and resulting in weak acceleration. It may even impact the lifespan of the exhaust system's catalytic converter. Once the catalytic converter becomes clogged, the car's acceleration will weaken, and fuel consumption will increase.
