Hello. I think i have fixed the problem. I have found that i have a missing oring... now the misfires are very rarely and i have only at the starting engine for 30 second and the running is very bad... I have checked and i have -13 for injector 2. I have used an aditiv for cleaning and now is -10, and at idle the running of engine is not smoothly.

The deactivation of the 2 cylinders is annoying. There is a jerking sensation when it deactivates. Could it be related to the misfires being on cylinders 2 and 3 where the deactivation occurs?

Hello. Since I started using premium gasoline, the misfires have become less frequent, if they used to be daily, now they are about once a month

So it won't help anything at all

Should I also put an additive in the tank specifically for cleaning the valves?
