Trying to determine which is causing the other. I have no interest in cleaning the VVT. I'll simply replace it. I appreciate the reply, I'm a BMW and Ford guy. I've been around the block a few times with timing on those makes. Just trying to get my bearings with these FA20 engines. The only thing I have yet to try is an engine flush. I have a bottle of LiuqiMoli Flush but I'm not a fan of anything that compromises the integrity of lubricating properties. This is a fairly low mileage engine (51000). Again thanks for the reply and if I'm not specific enough please just let me know what other info you need....I will gladly supply it if I'm able. That's why we are all here.

I'm just irritable today
From some quick googling C1201 has come up do to runnability issues in other threads so I would focus on the P0000A and not worry about that code. Here is an example on that caused by a P0301.

There are some confirmation driving pattern procedures that can be done but you need techstream to do it and have no experience with techstream. They look like they are just confirmations tests after attempting fixes.
The listed fixes are:
move/replace vvt solenoid(done)
engine flush
valve timing(doubt this has jumped)
oil control valve filter
cam gear
ecu
I'd try the flush next. If that doesn't work it sounds like it's either the OCV filter or the cam gear. To me I would check both at the same time due to how far you have to take the engine apart to check either. Might as well check valve lash while in there too. As far as any other less intrusive tests I don't really have much idea. It doesn't seem like a common code that pops up. A lot of the threads on it are dead ends.
