ok i been searching for a few days now and haven't found anyone that has fixed this problem. Maybe someone can help . The problem i am having is engine light came on , checked codes got a p2099 and p0306 . Truck is running ruff, start's to shake and power loss at times.

Would a 02 sensor cause that ? was looking at the one behind the cat passenger side and the blue wire is frayed. Oh sorry it's a 4.7 and i just put new head gaskets on it, new plugs, rad and stat, water pump. Any help would be great thanks.

 

You can Google the DTC codes and see what they are.

You can also download the service manuals from the links in my signature and find them in there also along with resolution steps
