Hi, my car listed above is over fueling, cranks but takes very long to start then it just cuts off after few seconds. I've noticed there's oil (just a bit) around the first 2 spark plugs. I'm not sure what to do. Friends are telling me, throttle body is dirty, change the air filter, some saying the valve seals are gone, rings and bearings. So at the moment I'm confused because I don't know much about cars when it comes to mechanical.

Hello,

It looks like you will have work your way through a few possibilities.

First back to basics.
To start get the engine codes read, a basic check to see if there is a possible sensor fault.
Things like a faulty engine coolant or intake air temperature sensor can cause hard starting and over fuelling. You can purchase a cheap OBD code scanner, best for Fiat is the Multi ECU Scan
Next, remove the spark plugs , check their condition. If needed fit a new set.
While the spark plugs are out perform a compression test.

If compression is good, then fit the spark plugs.
Check condition of the air filter.
A blocked air filter could cause bad running and over fuelling issues.

The oil around the 2 spark plugs would be caused by a leaking valve cover gasket
