I'm currently working on a 2002 E-450 7.3l powerstroke. I recently replaced all 8 injectors due to 4 of them failing the buzz test and no power until truck was warm.. Once injectors were replaced, there hasn't been much of an improvement whatsoever. After warming up for 15-20 mins, the truck seems to run a lot better. Below is a list of all parts that were replaced while installing the new injectors... Any help would be appreciated, i'm at a loss. Truck occasionally throws the P1211 code while under load and shows cylinder #1,#2, and #6 weak under cylinder contribution test. Truck has 115k miles
