Stopped in a traffic light and while i was shifting to 1st gear the rpm's went crazy on their on, without even touching the accelerator, only by pressing the clutch. They went sharp and roughly till 1.000 - 1.100 fall down, went up in a strange way - as if someone was accelerating in a progressive, smooth, way - and fall down again. Could this be just a simple "poor gas quality" issue or is it something bigger? Any ideas?

 

Try cleaning the throttle body.

 

Done it already tech. Nothing there. As the past days i didn't notice anything similar, i think more and more that it was a poor gas quality issue. I don't know how things are with gas in other places but here... at fisrt you have to trust the gas station owner and the firm he has!!

 

OK keep us posted if it does it again.

 

I will. Thank you tech.
