While travelling to work today down the dual carriage way the UNO started to lose power, I then realised I still had the choke out after 6 miles. I pulled over left the engine running and then continued after a couple of minutes and all seems well, till I got off the dual cariage way and the UNO died. Continued my journey to work on foot, got a lift from a friend at work and the uno started first time and was OK on the 10mile journey home.

So any ideas why it should die on me, and what a crap place to put the choke, so it cant be seen from the drivers seat, I know its the size of a small ashtray,when extended but cant be seen while driving due to the steering wheel.

It possible you're suffering from carburettor icing[:0] now the weather has started to cool down a bit..

Obviously not, if you've used the car during the cooler weather before ( and the little corrugated alloy tube is in place from the exhaust to the air box ).

I'm guessing a bit, as I don't know which engine your Uno has, but it might be a cheap, quick, fix just to replace that pipe.

I have been having the same problems, I own both a uno and a panda. The uno, see post below, was loosing power and then dying (no kangarooing), I would wait 30 seconds and then start her up fine! Same thing was happening on motorway when pulling hard.

I am now driving the panda to work, and it is doing exactly the same thing, at exactly the same place on the way to work!! What the hell is going on?

I then read John's post and started to think - Man, I don't have those corrogated tubes on either car....

Will let you know the results.

Well the theory about the choke being left on has gone out the window. The same thing happened again, I got off the dual carriageway and it died in the same spot, would not start so left it 5 mins and away it went again. I have the corrigated pipe fitted from the manifold. I have the 993cc fire engine the car is 1991.

pothole, I have the exact same engine 999cc fire in both the panda and the uno. Hopefully someone on this board will come up with an answer - this must have happened to someone else!?

An electronic distributor (rather than the one with a set of points in it) can cause it to stop when hot, and be OK again when cold...
But I wouldn't expect the Panda to have one (as standard fitment) unless its a 4x4.

I've replaced the distributor in my '93 Panda.
Lashlondon has also done his in a '91 Uno.

Both with the 999 Fire engine.

Unless somebody has fitted one, as I have to my Panda ... (which moved under its own power today btw; it even stops too)

Well done Steve - get it done before winter sets in

Woohoo! Good one Steve.

I am hoping that my stopping problem may have been down to the hot electronic distributor as John H suggested, in a previous post I mentioned a small water leak, and I did notice at the time my heater was not working.
So hopefully now that its filled with water and I sort the pipe out I should have no more trouble.
I am still fairly new to the car and appreciatte the help I am getting from this forum.

pothole.

Got same problem !
Chilli days setled in alright

hrm carb icing [:0] my alloy pipe is missing too ! good idea ! I will replace that and see !

Thanks !

YES ! that was the problem ! Thanks !

I also went and asked a good friend of mine who is a mechanical engineer.I can't remember much of the technical stuff he told me but the bottom line is that this aluminium pipe from the manifold to the air filter needs to be there. Most people or mechanics take it away and that mainly happens in the countries that are hotter. If you live in a hot climate you don;t even need it. What happens is that the air filter (The original one for the Fire angine anyways) has two inlets for the air. One is coming from somewhere which will be cool like next from you headlight or something and the other comes from that manifold pipe which produces hot air.
What happens is that big filter box has a mechanism inside (if you open it you will see for yourself) that has a temprature sensitive spring. This spring controls the two inlets of the air from the two points (hot/cold) so that your engine takes the correct air temperature. If you ask a mechanic they will say that the colder this air that goes to the carb is, the better for the engine and the more power you get. what happens during cold days though is that carb gets icey and needs a bit of hot air for that reason. (By the way the hotter the air the more fuel consumption you have) SO in a few words you need to have that soft aluminium pipe from the manifold to the air filter box so it supplies hot air when needed so the carb don;t freeze to death and stalls your car.

I put mine yesterday and oh boy what an improvement I saw ! I drove quite a few miles to work today 6 o clock in the morning on the motorway where it was freezing cold and the engine was running more than perfect and the best I have seen it run in cold days since I bought the car.

I don;t know what happens if you have put your own filter but I think someone else who knows more can give a solution to that.

Thanks guys if it wasn't for this forum I would still have the problem.

Cheers

You're right about the aluminium pipe...but I live in Italy and the lowest temperature here is 0°C so I never experienced problems without that pipe!Dou you know if this problem may affect the fuel injected fire engines[8)][?]

Hei.

I've got an 1108 FIRE engine sitting in an Uno from -93. The car runs smooth without the pipe, even in -25 degrees (Celsius). I think it's -13 degrees Fahrenheit if it's of any interest. Anyway - cold... The injection module is made by Bosch, and is a SPi.

My own Panda's the 999fire engine with breakerless distributor(Bosch SPi injection system)...but I know there are some cars with Weber/Marelli injection and no distributor (the ECU manages both the injectiont and ignition)

Carburettor icing is worse in carbs than it is in injection throttle bodies:I : with injection the fuel is squirted out at maximum rate for a relatively small number of milliseconds, rather than a continuous fine spray which does the "cooling by evaporation" thing rather better in a carb.

As the OP has a choke, I assume he's got a carb too
