Thanks for replying, I do not have oxygen sensors, pre cat only temperature sensors, that is my dilemma

No vacuum leaks, idle is perfect, but when pushing it on sport mode I even smell the gas

Obviously it's lambda or o2 sensors related but I do not have them, in oem manual they described as temperature sensors or lambda zonde, I bought brand new sensor 11781427884, but his plug just does not fit, and seal color of mine are yellow and new one is green.

Yes, just viewing that on realoem.com Have you checked and cleaned the MAF? Enter last 7 of VIN on realoem for actual part# needed for temp sensors.
