I am very desperate!!

My Fiat UNO (with fuel injection!!!)

Type: UNO 146 1000/1300 T
Trade name: UNO 1,0 S 3T
Test date: 28.03.1989

always dies, as soon as I go from higher rpm into the idle speed!
But when the engine is in idle speed it works fine!
The car already was several times in a garage, because of this problem!
This effect is worst, if the engine is still cold.
I think that the Choke does not work correctly!
In the garage the idle speed controller and any distributor were already exchanged!
But the problem remained further!!

I am not a mechanic, so I cannot say you exactly which parts were exchanged!!

I have already changed the idle speed screw a little bit! But the engine still dies,
if I go from higher rpm into idle speed!

What could be the problem?? It would like to know gladly exactly,
so that I can make exact instructions in garage!
Because up to now the car was in a Fiat-Garage to eliminate the
problem and a private mechanic also did not find this problem!

I would be grateful for a rapid answer!

Hei.

I have an Uno with injection as well. But no idle speed screw. Anyway... this you can do yourself:

Remove the air filter box. The whole thing. And clean out the injection unit - it may be called throttle body or something. It is propably contaminated with oil deposits and dust. This may clog the "vent" that delivers air and fuel to the engine, making it stall when idling.

Try it yourself. It´s cheap.

I have removed the air filter box ,
and cleaned the incection unit a little bit!!

But the problem remained further!!

Hey Topicstarter,
do you still have the problem? Because i had.. and sometimes still have..?

This thread is over 5 years old...

Old thread.

Replace the vacume sensor thing on the distributor, or atleast check the hose to see if its split or even attatched. A fault one of these or a leak can cause stalling at idle.

are you sure your just not stalling it :s
