Hello the wife has just got a 500 twin air. It's a 11 plate with 60k.

She loves it but it has a idle issue? Runs lumpy like it's on just 1 cylinder?

And do they always sound like the exhaust is blowing?

I'm sure I'm going to be here alot the fiat thing is new to me being a ford man lol

With only two cylinders it does idle a bit lumpily and the fresh air valve does fart, particularly when cold.

D

It will idle fine and then sounds like it goes to 1 and a half cylinders? And sometimes will stall no engine light?

Stuck new plugs in it today Ngk iridium but it's still not right?

I'm thinking it could be a coil pack breaking down.?
