Technical Punto evo 1.4 2010 jolting

[Nando6]

Hi all,

So Im having an issue where the car will driving fine for a while till all of a sudden it jolts/jerks massively as though its going to stall but started but up on the starter then the start/stop unavailable messages come on the dash.

I’ve also noticed that the temp gauge seems to take a while to get up to temperature.

Does have codes for multiple misfire but engine seems to be running okay.

Any thoughts?

Thank you

I'm no expert, but I recommend looking into coils, spark plugs and driving belt also fuel pump. And which 1.4 engine is it? Multiair? Could be a bad multiair brick too. How often do you change the oil?
