Rough engine start/stop

I did the throttle body cleaning with the car stopped, means I can remove this one from the list.

My guess it is also that the box it can be the reason. Normally I was tightening that 10mm clamp with a flexible screwdriver, but today I did it with a spanner. Also few times it was happening that, after I was taking out the box, trying to guess the reason or find a solution, the pattern of the engine shaking was changing.
I will monitor tomorrow and come back with reply.

 

No, it is fixed very well.

 

I guess I found the problem, but I need to monitor during the next days.
Yesterday I was tightening as much as I could the clamp between the throttle body and the air filter box. This morning I noticed the shaking again changed and decreased. I will try to replace the rubber gasket and come back.

 

I was just guessing, but the problem is still there.
Outside temperature increased also so the problem is not that bad anymore. I will try to do a compression test.

Can an overfill of oil, or a bad type of oil cause this problem ? Last time I did it, I haven't been at the Toyota dealer and didn't check properly the details.

 

Right now it is exactly at 2/3 mark on the oil stick. Not losing oil, but in the last months only my wife drove the car and didn't check it. I will try also an oil change.
