6.0 issues
My truck is an '05 F-250 6.0, 6 speed. It has recently been bucking under acceleration when the engine is cold. Once the engine is warm it runs fine. I also think the glow plugs or the relay may have problems, as it wasn't starting well back during cold weather. Wondering if I may have ficm or injector issues as well? Any way to diagnose these parts if they have problems? Thanks!

Weak or bad batteries will kill the FICM so if they are old over 3 or 4 years need to get some new one should be 850CCA
Sounds like it is bad, need gauges like the Edge CTS or ScangaugeII they will read ficm plus alot of other stuff.
