I am to believe the solenoids were oil starved because soon after resetting check engine multiple times and starting up my car revving and turning off seemed to make it go away. So far idle is a bit smoother.

I read some where that it could be oil pressure would throw the codes. I noticed I had a leak on my oil level sensor and replaced that. But codes kept showing up. Buying the sensors to see if those are the issue. I read the guide you sent and seems difficult to pull those out to replace. Worse comes to worse I may have to removed them.
