Guys!

The Cinquecento is giving me a hard time.
Not sure if I'll continue investing in it because the problems just keep coming. I don't mind 'fixing it up', but it would be nice if it would work for a month or so...
Nevertheless, I like the car so here goes nothing...

It has been idling slightly weird lately. Sometimes 2000rpm, sometimes 1500, sometimes going all over the place. Usually lasts between 5-15 minutes but it seemed to be getting worse. Recently the car wouldn't start properly and ran rough. We thought it'd be a coil again but those work fine.

After some research we decided that the car gets way, way too much petrol. It's simply choking on it. Once it's up to temperature it drives fine but if you are stationary and press the accelerator in neutral, you can actually hear the car choking on its petrol. Driving behind it confirms this idea, it smells very, very petrol-y.

Anyway; Is it logical to link this problem to the high revving? Is it maybe the automatic choke that's completely messing up? What regulates this?

Help!
 
First thing I would check is that the pipe connecting the map sensor (bolted onto the same mount as the ecu) and the inlet manifold/ tb is not cracked or damaged.

I also happened to me. Try this:
- Disconnect the plug from injector. If it starts, let it run, if it runs more than 2 minutes, you have either a broken injector or an weared o-ring. To me, happened to solve my problem gettin a new o-ring in the injector (the one return way).
Hope this helps.
