I know the ICP sensor will shut you down.
The cam sensor is another one that more problematic with the 7.3's but still an issue for the 6.0's.
The EGR just causes loss of power at least in my case that's what happened.
These are just a few that seem to come up other than turbo issues. When I'm on a real tough road, my hands sweat from the fear of being stranded not the sheer 1000 foot drop off
Mike, they just told me there is a different extended warrantee. It doesn't cover as much but would cover all that I posted above...unless they made a change since August.
I'm also thinking about non Ford Warrantees...know anything about them. I would love to cut the cord with Ford.
