I have a an 3.0l v6 which I just did a tune up on myself.

I've got a few things going on.

I have random codes that pop up and don't return when i reset them.

P0171
P0174

I have a consistent
P0431

And now I have an intermitent random misfire code
I've seen misfire codes for all cylinders at this point. I notice that one the passenger side I had oil in one of the cylinder wells. I have not had an oil leak anywhere but I do seem to burn quite a bit of oil, about 1QT every 1,000 Miles. Any help questions or suggestions. I would love some help.

Start searching for vacuum leaks and the last code might go away too.
