Thanks for asking your question. I will try and help you out.
It’s very possible it’s an Iva. I’ve seen it many times. If it is, sometimes you can cut out one cylinder at a time to determine which cylinder is misfiring. Then swap the Iva housing to another set of cylinders to verify it’s an Iva.Please reply back if you need more help. I am happy to assist.

you think I need the whole house ing or just the solenoids was thinking about just replacing all of the solenoids or will that not do any good
Technician: Cat Man, Cat Engine Expert replied 2 years ago
I would not suspect a solenoid. Normally when it’s a solenoid there is a code.

Why when it warms up does it run fine
Technician: Cat Man, Cat Engine Expert replied 2 years ago
The Iva and oil get warm.
It could also be a head gasket. I have seen them barely blow and only run poorly when cold. When it gets warm. It seals back and runs good.

I presure tested it a wile back looking for Leaks that it had around the oil cooler held 20 psi for over half a daySeems like this only happens when it’s a little colder out side
Technician: Cat Man, Cat Engine Expert replied 2 years ago
Many times it can blow and not get into the cooling system. It blows between cylinders.

Cat man I do have some inactive code for the Iva
Sid 284 fmi 7 flash code 94
Pid 385 fmi 1 low intake valve actuations system oil pressure
Customer reply replied 2 years ago
Do you have any suggestions for these codes
Technician: Cat Man, Cat Engine Expert replied 2 years ago
Can you double check 284-7? It’s not on my list.
385-1 is low Iva system oil pressure. This is often caused by a large oil leak at an Iva
