Check for vacuum leaks.
Plenty of information in the forum.

yeah i dont know what is exactly doing this, everything in place, i just took it to get oil change from a European mechanic, everything is intact

i took it to a shop to check for vacuum leaks, they said they couldn't find any leaks like that, but they did change my coil/sparks due to misfire thats now fixed and its still doing the same.

With the engine idling, pull open oil filler cap, see if there is a lot of suction, may be the "pvc" valve on the valve cover. Now, if the engine dies when you open the cap, I'll leave that one up to the gurus on here...

If the suction is "noticeable trying to hold down the cap", you got a vacuum leak.:shifty
