05 Mustang V6 fuel pressure reading high

It's a coworker's car, it was randomly sputtering and left her stranded a couple of times. I found that the fuel rail pressure sensor connector wasn't getting a good connection, so I bent the contacts and it was good for a week, then started acting up again. It would read low to mid 40s when it had a connection, or 75.1 when it didn't. I replaced the connector and now it reads high 60s to 70, but runs fine. Any thoughts?
