No errors stored for MAF, here it is bloody expensive (140pounds with discount)
so will try to find a used one.
I never cleaned the egr (never was able te remove the inner part of it)
I did clean the manifold (wasn't very dirty and the outside of the inner egr part).
I can move the piston easily by hand if I push that metal knob in the middle of the egr so I guess the egr is fine and not stuck.
This hesitation is not constant it happens here and there but is annoying when it happens.
