Yes it contradicts because I haven't explain it properly. Sorry about it.
It looks like plugs were making issues because I changed them again and there isn't a misfire at idle when cold anymore.
Do you have any idea why I have been experiencing a misfire at idle when engine gets warm? It's definitely not related to spark plugs, leads or coils. No warning lights and no errors.
I want to resolve this issue for the past 2 years without success and it is getting worse over time. On cold start rpm at idle is 1000, then when engine gets warm and it drops to 750 misfire is starting. There aren't fluctuations at RPM at idle once it gets warm.
Asked hundreds of people and no one has any idea why it happens. Some people in the other thread I started mentioned crank position sensor, but if it is the culprit I wouldn't drive the car for 20k miles with a bad one.
Any help would be appreciated
