No power underload and running lean.
Just a heads up to folks about the issue i had.
1st I have 2005 f150, king ranch, super-crew with 5.4 stock expect tires with 190,000miles. When going up hills and accelerating hard it would misfire or seem to loss power. After about 1 week of this, a check engine light came on. I Check the code and it showed to be running lean. I read and read and the best thought i had was spark plugs so i had them changed at the dealership and 2 broke off wish total to be 448.98 for everything. After all this i must say wow this truck is back from the dead feels great and mpg has came up also.. Hope this helps someone like this forum always helps me
