Thanks xviper,

now i'll biriefly explain :

-Heat soak, leading to triming retard , happens more in hotter weather, cold weather, it happens but with less power loss. More it's driven, looses more and more power.

If you read the past threads and posts you'll see what i did to eliminate problems, now i have questions about
Knock Sensor
Intake Temp. Sensor
Coolant Temp. Sensor

any ideas? might they cause something?
PS: If i disconnect the knock sensor, would the car work?

 

Locking, due to multiple posts of same problem.
