Before I started disassembly it threw a check engine light, rough running and smells rich running. Misfire on 5 and 6 and the intake manifold pressure sensor was showing a number higher than spec at idle. I did find a cam position sensor connector may have been loose and one of the intake manifold gaskets had a tear in it (possible leak).

All of the timing marks are lining up. Once the cam hold tool arrives I'll pull cam covers to see if I can tell anything else about it.

The fault codes came up once the wife stopped (engine running at idle) after having been on the interstate running fine at around 80 mph for about an hour.
