Started no notice it was losing power when accelerating to merge onto highway. Notice this next time I drove it and check [engine](/topics-engine-ford/) light came on. Code reader says it has a P0191 code fuel rail pressure sensor. Tried replacing the sensor but it changed nothing. What should I do next? The truck starts every time no issues there. You only notice the issue when trying to pick up speed to merge onto highway for example and/or when climbing a hill. It really lags when climbing a hill. Mechanic's Assistant: Does the light stay on, or does it blink? The engine light? It stays on Mechanic's Assistant: What is the make/model/year of your car? 2009 f250 super duty 5.4 Mechanic's Assistant: Are you fixing your F250 Super Duty yourself? What have you tried so far? Myself I hope tried changing the fuel rail pressure sensor but didn't fix issue Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I dont think so
