Looking for an experienced Ford diagnostic mechanic for my 2005 Ford F‑150 Lariat, 5.4L Triton V8. Mobile service at my house in Belmont preferred.
Im done playing around with this code. I want someone to solve the problem. Prefer to pay by the job, not by the hour, sfter s diagnosis. I want the problem fixed and we’ll get the parts needed. Not make the light go away and have the same code come back and a couple days or a couple weeks.
MAIN PRIORITY: RECURRING P0191
The fuel rail pressure code keeps returning despite the sensor being replaced. It typically comes back after approximately 40–50 miles, especially during sustained highway driving above 70 mph. Wiring concerns were previously noted.
I need someone who can test actual fuel pressure, compare it with scanner readings, and check the sensor’s power, ground, signal, connector, and wiring to find the underlying cause.
SECOND ISSUE: P2112 / P2104
After a Roush cold-air intake and PowerAid throttle-body spacer installation, along with an engine pressure wash, the truck entered engine failsafe mode. It currently runs normally, but a scan showed stored and pending P2112 (throttle stuck closed) and P2104 (forced idle).
Need the recent installation, throttle operation, connectors, and wiring inspected.
The scanner connection issue was resolved after replacing fuse #41, and the truck can now be scanned.
Please reply with your Ford 5.4L diagnostic experience, equipment, diagnostic fee, and earliest availability. Looking for proper testing and a clear diagnosis rather than replacing parts based only on code descriptions.
