Hi iv got a punto 1.2 8v on a 51 plate and its misfire coming up with p0300 random muliple misfire and the odd time comes up with p0302
It all started when i had my timing belt done but i thought it was all down to my lambda sensor going as my cat had been blowing for some time so the next day i replaced the whole exhurst cat aswell, replaced the lambda sensor.
Then it seemed a little better but still a slight misfire so i relaced the spark plugs, replaced the coild packs but only have a new ECU and coil pack 2 years ago but change the coils anyway.
Then that dint work so checked all HT leads pulled them out one at a time and misfire was worst after pulling each one out and the HT leads was sparking fine.
So i thought it might of been the injectors so iv just replaced them and still doing the same also put a new throutall body on
So am abit stuck and need help only thing i can think of is inlet manifold but can not hear any leaks
HOPE SOMEONE CAN HELP PLEASE
THANK YOU MARC
