Lack of Power Blue Smoke on 2003 6.0L [NOT EGR VALVE]
Hey guys, hoping someone can help. So far its been to two dealers and a handful of my buddies that are techs.
Around 2000-2500 RPM the truck will start missing. Lack of power and blue smoke are very evident. Gas mileage is down to 10.5 mpg. EDIT: This is only an intermittent problem.
Stuff that has been replaced recently:
What has been done so far:
The FICM has been checked and is good.
Passed Injector buzz and drop tests.
All vitals appear good (used a mastertech CAN box connected to a laptop)
Recorded a snap-shot of the truck missing, what I see is when the truck acts up the Fuel Level % is all over the chart (from 17%-80%). I know this shouldn't affect performance but when the Fuel Level drops like that so does the ICP.
Anyone have any ideas?
