Hello, everyone
I've been searching and searching all over the interwebs to see if I could find a pointer as to what is wrong with my car. I'm hoping some bright minds here might know what I should do, or maybe identify a cause. I'll explain my issue in as much detail as I can.
Our shops here in Norway charge about $200-$300 for a simple diagnostic, so I'm not quite in the mood for that quite yet.
My 2010 Fiat 500 1.2 Automatic has two major issues, they might be related:
I should mention, I feel I have to drive it in manual. There is no start/stop on the car.
Starting the car.
It sounds like it's not firing on all cylinders, or doesn't get enough spark: it cranks and cranks and speeds up more and more over about 5 minutes before it finally runs. If I let go of the throttle in neutral, it stalls. It also stalls in gear if the RPM is high and I let go of the accelerator completely. Sometimes, it manages to "catch up" and the engine shakes on about 500 RPM, before going up to around 700 RPM idle. But most of the time, it just stalls. I need to say I feel it starts a little easier when depressing the accelerator a little when trying to crank. There is a strong smell of unburnt petrol every time.
Stalling when driving.
When driving, the car seems to lose power on gear change sometimes, mostly downshifts. It drops RPM momentarily and after a second, a hard yank is felt and it regains power/RPM. When I slow down, approaching intersections I have to watch and feel the RPM then downshift manually to 1st gear to try and avoid stalling while braking very carefully before a full stop. If I try to move an inch further and stop in these situations: the RPM goes up, drops fast and it'll stall.
The engine starts fine(ish) when I need to start again after the stall when driving.
OBD error code I've found: P0560 System Voltage Malfunction.
I deleted this code, and it did not reappear.
What I have attempted so far to mend the issues:
Behavior of the car is the same.
Do any of you have any ideas?

What I have attempted so far to mend the issues:
- Sparkplugs changed, all four (one was damaged)
- LAMBDA changed.
- New battery.
- Tightened ground on starter.
