Nate and Dave,

I forgot to mention that I "fixed" the MM hose yesterday with teflon tape,
duct tape and cyanoacrylate and it shouldn't be leaking anymore right now.
Also, as maximum seen boost on my analogue gauge is 0.3 Bar (or 1.3 Bar if
that was a digital display) I doubt there might still be a leak there...

Furthermore, the problems started after filling the tank with some not
really excellent quality fuel so I wonder if that's not the cause of my
problems.... I don't know if the ECU would throw a knock sensor code for
bad quality fuel but it's supposed to normally me thinks...
