synthetic oil and rev x will only be a band aid fix for so long. I got another 30k out of my injectors before stiction came back and didnt work any longer and then it was time for injectors... but now as a preventative measure I use rev and an 5w40 synthetic at every oil change.

Warren diesel can rebuild your injectors for about the price of two ford remans btw

Ok it finally trew a code! Ficm operation? This just started when I put the extreme street tune on it from innovative. Any ideas?

First thing I would do is check ficm voltage. Idk what you have to scan for codes but many scanners can read ficm voltage. If not there is a way to measure it with a meter across 2 bolts on it. If u google ficm voltage test or something you should find it.
