My Micra was running a bit lumpy, nothing terrible but a bit jerky on acceleration, very annoying. So I went looking for a cure.
I read somewhere that if you partially block the vac hose with a rubber bung that has a 1mm hole in it - running and acceleration immediately improve. So I tried it.
And it is correct, no more lumpiness, car pulls quicker and more smoothly.
How can this be true?
