Did you ever fix this problem? I know it’s 11 years late but I have a similar issue with my 1.4 auto lupo, engine fault codes are P0300, P0301 and P0302.
P0300 Mulitiple random misfire
P0301 Misfire in cylinder 1
P0302 Misfire in cylinder 2
We have changed the spark plugs, HT leads ( this is NOT the BBY engine), coil pack, checked the oil level to make sure it wasnt over full, changed the MAP sensor and we have cleared the codes and within 5 mins of the car being on idle they all come back on. It runs sweet for 5 mins til it starts to misfire again. we haven’t checked fuel filter or injectors as this is my next move. I just don’t want to throw any more money at it without someone kind of direction!
Any and all help is appreciated!
Thanks in advance
