You could also try polishing the spool valves your injectors first before dropping coin on 8 new ones, will only cost you time and 8 injector o ring kits. There's lots of clips on YouTube showing how this is done...I don't think sticktion is causing your high icp numbers.
I thought about doing that, I've watched tons of videos on it but I'm kind of scared to be honest. This morning the ICP wasn't as high as it normally is. It was bouncing around in the 1400s. What is the normal ICP for cold start idle and EOT idle?

Icp and ipr% is always higher on cold start
Test hpo system post numbers
Do a bubble test cold if it passes then you most likely can clean inject

It really isn't that bad of a job to do. Two words of caution is don't reverse the spool valves upon reassembly and don't over tourque the little torx nut and bolt that holds the coils on. I went to tight the first time on mine and caused a random rough idle condition when warm. Word on the street is they only need 1/2nm which translates into about 3/8 foot pounds.
