Hello all, I am here to seek information to enable me to help my daughter maintain her 2016 Fiat 500 1.2 Pop, which has never been officially serviced (I have changed oil, filter, brake pads etc, but it has never been near a Fiat dealership from new).
So, the latest problem is a slight roughness running at lowish rpm (e.g. it pulls smoothly enough with some rpm but at anything lower than 2000 rpm it feels a little lumpy. I have checked the plugs for colour and any signs of ignition problems, nothing seen, it seems to be running ever so slightly lean to my way of thinking (plugs are light brown rather than chocolate brown) but that's it really.
Air filter looks reasonable
What is the easiest and cheapest way to determine if the throttle body is working properly ? (I have a basic OBDII reader and no codes are stored presently) or otherwise diagnose this fault.
