Hey everyone i currently am having a issue with my car shaking after its been sitting for a period of 10 hours or more. It usually happens 80% of the time. Here is a list of what has been replaced on the vehicle so far.

Valve cover
Valve cover gasket
Two vanos solenoid
Six coils
Six spark plugs
Valvetronic motor gasket
O2 sensor

This issue is frustrating me so much im at a loss for words. I have researched and researched to no solution. When the car shakes it is the engine and the car moving like a left to right. Every once in a while a 2A82 code will come on but will go away as soon as the car heats up and when i turn it off and on just dissapears. I know the code points to the vanos solenoids but since they have been replaced already i cant help but wonder if i have a timing issue with my cams or something. Im hoping this isnt the case due to it being a unreasonably high expense to have a expert look into it. Any ideas anyone??

Have you considered the possibility of an injector leaking overnight and the misfire being caused by excess fuel (which burns off, so that the engine then runs normally)?

Remove your plugs when cold and inspect for wetting.

I had a similar problem. It was my eccentric shaft sensor.

This is my biggest fear due to me having to completely remove the valvecover again and replace. I knew i shouldve just did when i did valve cover it just sux because im already 1500$ into fixing all these issues and now this.

I will ask the car shop to look into this issue where its currently at.

Take off your engine cover and make sure nothing is leaking. My oil cap was leaking, and oil was dripping close to the sensor. Could be your case. Nothing electronics cleaner and a new cap won't fix. I doubt you broke it already.
