Okay, so.. $10 paypal to the person who helps me figure this out! 2007 Mustang V6 Automatics transmission. Got the code P0193 for Fuel Rail Pressure Sensor. Car still ran fine. Figured I would just change the sensor. Bought a new one and installed correctly, now car starts but just idles and lugs. If I push on throttle, the rpms barely go up. OKAY great so then I decided maybe just a faulty sensor, so I put the old one on correctly and still same problem. I checked the fuse relay to make sure it was good and placed in, and the inertia button inside near the dash. What could possibly be the issue or is there something I missed?
