Ok, I have been reading all of the O2 posts. P2196, p2197 and p2198 posts. I read them all back to 2010. And yellow roush post. And all the recent ones. I have all of those codes. 2005 4.6l 3v gt.
so far I have added fuel injector cleaner, replaced fuel filter, pulled and cleaned plugs checked all COP's the plugs and COP's are all brand new. Problem started over the winter. I did find a vacuum leak from manifold to brake booster. The hvac/ and cruise do not work. So I'm thinking vacuum leak. Check the O2 sensors they are correct. Have a video with my crappy scanner. Here it is.
