Hello. I just rescued a cinquecento from being crushed. It ran terribly and still has lots of power loss. Worse when it's cold. But I was wonder which of the plastic hoses go to which on the intake. Can it be the fault I'm having?

Welcome to the forum
Does this help? https://www.fiatforum.com/cinquecento-seicento-guides/146381-spi-throttle-body-where-pipes-go.html

Not quite there i meant on the plastic bit ontop of an 1.1 Fire engine. I have a brown and black end from either the throttle body or the vacuum bit of the hose doing to the front. Where it would let manifold heat in

Hoses to here

can you post some, er, 'wider' shots Fumpen..?

Someone WILL know what that is; but I don't...

All I know about that is, when people install an induction kit (and therefore remove the airbox), they tend to just block the pipe. As long the hose is in good condition it's unlikely to be the cause of your issue.

Cinqs are very basic, an air leak leads to high revs, not a lot else.

Is the management light on?

Just after connecting these pipes up on a 1.1 seicento sorting out a vacuum leak. I connected the brown pipe to throttle body and "M" on the air filter box ( referencing the picture you have posted).

I then connected the black pipe to the "N" on the air filter box and the other end is connected to the smaller box on the start of the air inlet just behind the passenger side headlight.

Car is running perfect in this configuration and idles where it should.

Hope this helps and makes sense.

N = Nero (Black)
M = Marrone (brown)

Thanks and no, theres no engine management light on. The car just looses nearly all power around 3k rpm in any gear. And then jolts back to full speed suddenly. I've changed spark plugs and cables. And the distributor blocks. Or what their called.

Needs a scanner on it

But a 1996 Cinquecento, doesnt have a OBD plug does it? im having a hard time just finding fuses in it

It doesn't have OBD2, but it does have a 3 pin plug. MultiECUScan can connect with the right adaptors

If I can manage to get my 1994 899 to speak to a laptop...so can anyone. I am very old.

As said, Multiecuscan, usb lead and 3 pin adaptor, robert is your mother's brother.

cento's were always known for a lull around 3k, its well documented if you search through old posts, but what oyu describe sounds much worse than a slight flat spot. interesting, any update on this...

Yes changed to some high quality spark plug lead, which fixet the hard cuts, but kept til low power through 3k. though if that is normal i wont mess to much around with it. Thanks for the help.
