Uno 1.0ie start problems, plz help me!

Hi, thanks for your reply.

I knew tesco was cheap, i have tried a number of times, however, now, the best they can offer me is £1700. I am fed up with filling out form after form after form on the internet!! Any idea what made yours £800? I only have a 1.0 uno and only want TPFT, the costs are astronomical! How is anyone supposed to start driving?! I need to speak to someone who knows the legalities of being an additional driver i think.

Hi,

Some more information on my car troubles (please help!):

I have now found my uno 1.0ie "Start" only seems to cut out when idle once the engine has been running for a bit, i.e. the engine is warm. It will run for up to 5 mins no problem until it starts to get warm then revs up/down (only slightly as if it is out of petrol) and then cuts out/runs a little more and then does it again after a few more seconds. Does the engine being hot change any people's advice please? Incase it helps I still feel there is a little too much water coming through the exhaust.

Do i really have to change the lambda? (it costs a fair bit if it isn't that!) Which other sensors are suspect?

HOpe you can help me, i would be very grateful, haynes is rubbish on this model!

Paul

(p.s. thanks again in advance)
 
It maybe worth reading the post in the UNO section of this forum: Gaz has cut and paste something from a while ago.

If it is that, you should be able to prove "no spark" during the fault condition by having a spare spark plug and pulling a lead from a plug on the engine, putting that lead on your "spare", touching its metal body to the engine metalwork and getting somewone to try and start the car.
If you get a spark in your "spare" it's a fuel problem.
If not... maybe magnetic pickup, or coil.
 
Hi,

Thanks for your reply. I read the post before replying to my post but my car will start first time all the time including after it stalls?

Silly thing, if it were a computer i would know what to do to fix it....grrr!

In that case a cheap option to try is cleaning inside the throttle body and the edges of the butterfly valve.
There may not be enough room for you to get down inside there ( if it's anything like my 999 FIRE Panda ), if so, with the cover removed so you can see straight down the throttle body, while it is running squirt small ammounts of aerosol "carburettor cleaner" down there - try not to stall it :) - the sides of the body will change colour from black to dull alloy where it's clean.

This may not help you at all, but IME, it sorted out my wifes Skoda ( which the dealer seemed incapable of doing, despite ECU diagnostics ) and helped my Panda a lot too.

The symptoms on my Panda were:
a tendancy to flood/stall when cold
poor response to part throttle when warm.

The symptoms on the Skoda were:
tendency to be too rich when cold
occasional stalling when taking foot off the throttle - you could see the stepper motor suddenly open the butterfly valve to recover from the stall. Most of the time it caught it.
I think the butterfly valve was effectively more closed than expected by the ECU :)
