I just want to let everyone know a out my 2009 ford fusion 3.0 stalling. It was not the throttle body although I had P2105. It was the pcm diode at least 99 percent it was as I also changed the relay. Interesting thing I had B1318 battery voltage low. even when it didn't stall. My cheap torque app picked up the B1318 and an expensive snap on scanner didn't get that code. I
The car would only stall every couple weeks. As soon as I changed the diode and relay B1318 never came back. It's been a couple months since it stalled and I now have trust in the car. A cheap fix. Too bad I tried the throttle body first.
I hope this helps someone as so many posts never come back and say what the fix was.
