I bought a nice twingo 1.2 8 valve as a winter run about as I have a 21 Z4 30i
You can imagine what that will be like in the snow !
It showed a generic miss fire code and was very lumpy until warmed up then ran fine.
I changed MAP sensor
Coolant sensor
Still the same
I then bit the bullet took off the inlet manifold cleaned the injectors, they were ok and produced identical spray pattern
THEN I adjusted tappets
They were all tight
Compression test prior to adjusting 150 -162
Subsequent to adjusting 225psi
Runs like a dream now
I hope this helps someone
Happy new year
