Most car models have a fuel pressure sensor that controls the fuel pressure in the fuel rail. If one of these sensors fails, a trouble code will be stored in the engine control module’s trouble code memory, and if this happens repeatedly, the check engine light will appear on your dashboard. Check Engine LightĪlmost all modern cars use a full-time monitoring system to monitor the car engine’s sensors constantly. READ MORE: Car Losing Power When Accelerating? (Here’re the Causes) 3. Therefore, if your car feels slower than before, it could be a problem with the fuel pressure regulator. Both too lean and too rich air-fuel mixture will cause a drop in acceleration. The engine needs a correct air-fuel mixture to function properly. An incorrect fuel pressure causes the air-fuel ratio in your car engine to be either too rich or too lean, depending on the pressure. The fuel regulator controls the fuel pressure, and if the fuel pressure is incorrect, the engine’s fuel pressure will be too high or too low.

However, misfires can also be caused by a lot of other things, so you shouldn’t just replace the fuel regulator as soon as you notice misfires.
