Alright, I was able to knock it out last night. Not too horrible of a job. You do have to drain the radiator and disconnect the upper radiator hoses, heater hoses, and turbo coolant hoses from the intake. You have to remove the upper portion of the air box and the first part of the intake tube. You also have to remove the rear turbo outlet pipe. Once all the connectors are all unplugged from the intake you can unbolt it. You also have to disconnect the fuel line that goes to the hpfp. Removal and install of the intake is a 2 person job because someone needs to help pull the harness out of the way. Getting the fuel rails out is a little tricky cause they're in there tight. You may have to cut off a couple zip ties that hold the harness to the rails because you need the clearance. The injectors go out and in like any other.
I cleaned them all up and replaced the bad one. The injectors had some deposits as well as the back of the valves. Nothing a can of seafoam won't fix. I got it back together and it runs perfect now.
