Title: Miss fire help!
Post by: Lou5590 on March 10, 2025, 12:36:01 PM

Hi there sorry if it's been covered already, I have tried to search but havnt found anything that is the same as my fault! Here goes

I have a jazz 1.2, it's showing misfire on cylinder 2 and 3 and multiple misfires.
So far iv changed coil packs around, changed sparks, had the ecu tested (came back all good). Compression tested and all values around the 160 mark.
It's over fuelling - thinking possible because of the misfires?
I'm thinking but not sure if over fuelling injectors could cause misfire?

Any help would be greatly appreciated

I would recommend getting an auto electricion to check the coil pack connectors if you have changed all of the above. There maybe a break in the wiring of either coil back or ecu cables.
