Hi Jesper and welcome to the forum :wave:

An 'IE' engine is 'Injection Electronic' (translated into Italian) and just means the engine is fuel injected instead of using a carburettor. I don't know what a 'CK' engine type is though. Maybe it's Danish for the carburettor models?

 

[homus]

i'm told by a chop shop that the difference is that IE is multipoint and CK is monopoint injektion? But my Uno is a IE and monopoint?
Is there at all any Uno's with multipoint? dont think i ever seen one...

My Uno is a 91 1.4IE

The petrol Uno turbo and most probably all diesels are Multi point injection (MPI)

I don't know of any nat asp petrol MPI Unos

My 1.0 IE start was single point injection (SPI) which I'd guess is the same as "Mono Point" as Mono also means 1.

:yeahthat:

As Louie says! The only MPi equipped Uno, in the UK at least, is the Turbo model. All other 'i.e.' models are SPi.

I'm confused now, tomorrow I'll drive out there and look at the engine he has

Perhaps you can help me with the problem I have. I have read the forum, all 11 pages of bad idle, but none quite like my problem.

Last Sunday morning I was at the bakery and no problem there, but later that day I had to drive again and it was hard to start and could not idle at all, could only get it started with very much gas pedal. It can idle with gas pedal pressed a little but very roughly. No difference cold or hot. (The difference between this and the 11 other pages)
A have checked vacuum hoses for leaks, nothing there. The small hose to ECU fails nothing. Spark plugs are very black and sooty. Gas cable is slack and the button on the damper casing is pressed.
When I try to rev it up it have a tendency to "shoot" back up trough the spi...

Some good ideas out there?

 

[Kozmos]

even if they are not the spark plugs, you should change them, have you checked the coolant temperature sender? because he is the one that sets a richer amount of fule when the engine is cold. you should also do a little test, on the next day in the morning when the engine is the coldest it can be, lift the hood and give it contact but don fire up the engine, you should hear an electric motor pulling the gas, or you can even see it if samone can help you.

Did you check that your idle jet isn't blocked?

 

[homus]

idle jet?? what is that? is it the "thing" on the back side of the spi house that push the throttle?

 

[Hyperspace]

duh, soz, I thought it had a carb.

 

[homus]

Ok, here comes the solution if anybody can use it to something

I changed the entire spi house and manifold, complete with sensors and gizmos, and now it runs like newer before, clean and smooth.

Good day to your all:slayer::slayer:

Thanks for posting back to let us know the fix!

Now it is going well how about this. Just for fun.
One by one put the old sensors back on to see which one was the dodgy one.

I suspect that a poster above pointed to a possible solution when he/she mentioned the cold sensor. I had a very similar issue in my 90 Mitsubishi Lancer, it had a broken sensor.
