6.0 missing under load

I have a 2005 F350. 147,000 miles. I had a dead miss in the # 2 cyl. Traced down to the injector. Bully dog chip was showing a 0266 code. had my mechanic replace the injector. while he was in there he check the compression over 300. he test drove it this morning and says there is a still a miss, but not all the time like it was. there is no codes on the chip or his shop computer. He says it is missing when the rpm drop while its under a load. but if you accelerate it goes away. AGAIN THE CHIP AND HIS COMPUTER ARE SHOWING NO CODES. any ideas

thanks Mike

You mean the rpms drop to around 400 after you let of the pedal?

My mechanic is taking it to a buddy of his at the dealer they are going to hook the laptop up to it and drive it. maybe that will tell us something.

talked to mechanic, Ford hooked the laptop to the truck and drove it around. Bar graph showed injector #2 and #7 very strong +40. #5 +30, #3,4,6,8 weak +10 and #1 -40. going to change the #1 and hope that gets me by a little longer until 3,4,6,8 go out. These are Alliance injectors changed all of them 17,000 miles ago. I wander bad batch of injectors or something else causing causing the injector problem.

Test FICM voltage and install fuel pressure regulator upgrade (blue spring). I am sure those more expert than I will check in, but that is what would do.
