I have a 2004 f350 that last winter started missing not haveing the money to fix it i let it sit all winter. this summer when trying to start it i discovered the computer was bad. i had it replaced and the mechanic said that must have been my problem. the next day it started to mis here and ther after it was warm then it would go away the rest of the drive cycle over the next week it got worse.i brought it in and they were booked for the next few weeks but suggested the injector.so i changed it. after changing the injector i started the truck ran for about 30 min. just as the truck became all the way warm the same problem occured.from cold start it runs fine then warms up and misses with combustion imbalancw code. any ideas ficm tests 52

Bad injector. Scan it again and look at a power balance test to see which one is dropping out

Are you sure that you replaced # 4? Where was it located? I have installed in the wrong cylinder once. Got in a hurry and went back to GAS firing order. Did you use a new injector?
