What this usually means
Giulietta/MiTo misfires are often coils, plugs, MultiAir oil-control, injector or intake leak before engine replacement. Ask for cylinder-specific proof and compression data if severe.
What to ask the workshop before approving repair
- • Show the diagnostic fault codes.
- • Show photo/video proof of the failed part.
- • Give an itemised quote for parts and labour.
- • Explain why cheaper common fixes were ruled out.
- • Use/confirm: Alfa-compatible diagnostic scanner
- • Use/confirm: Compression tester
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
