Got a code on a 99F 350superduty. Code P1272 #2 injector. Got the code while running an injector buzz test #2 buzz sounded pretty punny. Truck also has a miss, so I'm assuming replacing the #2 injector will fix the code. Not my truck working on it for someone else don't want to tell the indv. to buy an injector if someone has a better idea. Thanks

 

1997 F-350 7.3 also experienced this/these codes. Replaced injectors 2 and 4 and still no fix. Glow plugs had recently been replaced and found a pushed pin in the connector into the valve cover. Expensive replacement of two injectors, but problem was the pushed pin. Check this plug if glow plugs and/or harness has been replaced.
