Good FICM voltage does not necessarily mean that the FICM is good ......
Typical Injector Problem... But Injectors are Fine
First of awesome site and I'v used it numerous times to enducate myself about diesels. My name is Omar and i have a 2004 (2003 engine) 6.0 with 180k, stock tune and absolutly love this truck!!
Ok so heres the deal.. The truck had a slight miss at idle on cold starts. once it warmed up in 10 min she'll be just fine. One day i notice she lost all power and wasent thr same truck anymore also some times at WOT she'll smoke white.. well i keep on driving and knew its time to pull the injectors. so about a week ago i turn her on, let her idle for about 8-10 min's like every day, head out the drive way and as soon as i give her some throttle she's somkin' like a train (except its white lol). turn around, park her and take the cobra to work
When i get home from work i pull the injectors and send them to a buddy. he tested them at diffrent temps, spool valve speeds, ect ect ect and they all came back fine.. soooo im kinda lost.. no idea what it could be
i tested the FICM before hand and it tested out at 48v where is should be.. any advice will be helpful as this is my very first diesel truck i ever worked on
