(T) Uno Fire 1100 idling slow to normalize.

Its good to hear that she`s slowly recovering!

The uneven idling is likely to be the other air leak, & dont forget to re-set the mixture screw after too.

You may be able to fit a vaccum advance unit from another small car, I did notice the vaccum advance on an 85` Peugeot 205 1.1 (Ducilier) distributor I had knocking about looked pretty much the same as the Uno one I had just changed.... shame I didnt notice it before I got the new one!

I know it can be hard to find parts like this where you are (its hard enough here these days!), so I think you should remove your vaccum unit (its not doing anything anyway), seal the hole so you dont get dirt or damp inside (maybe wrap some insulation tape round the body of the dizzy) & take the unit to some scrap yards to compare them.

The other running issue may be dirt inside the carbs float chamber, but it could also be electrical, I`d check the earth straps in the engine compartment, the distributor connections, ECU connections, the fuel pump etc.

It could also be the coil, they can be intermitent when they are failing, it can also be the magnetic pick up inside the distributor, or the wires from it inside the dizzy breaking up & earthing, but that usually causes intermitent non starting rather than cutting out during driving.

Check the earths & connections first.

Have you changed the fuel filter before?

Regarding the clutch, if theres no fluid leak, its likely to be an air leak higher up the system which will draw air in, possibly at the low pressure master cylinder end or the reservoir where it joins the master.

Hey guys,

Something amazing happened this morning. Early i woke up and drove to the neighbouring town to also try the scrap yard guys there. They also sell compatible spares as well from time to time. Got there and asked the one fellow about the vacuum pump. He took a brand new one off from a heap of new distributor they got the had problems inside. The vacuum pumps are brand spanking new, not only did he have the exact same replacement for me, but wait for it...he turned around and gave it to me at no charge.

I just stood there dumb struck at this story and after a few moment regained consciousness. I could not believe this. After almost 3 weeks of being done in by all these mechanics and taken for a ride that has cost me close to R3000-00 (more or less 230 Euros) this kind gesture just rocked up out of no where.

Any do, I drove back home and just finished installing it as per A73UK’s instructions without removing the distributor, reset the ignition timing and I can honestly not wish for more perfect. The accelerator response is live and fast and when I take my foot off after a rev, it almost instantly recovers back to idle speed. I am over the moon.

The clutch so far is also holding but I am going to check it properly now again.

It is just this random cut out that is still bogging me down now, I got a ECU ignition module on loan from the same fellow, a second hand one. I will however check the more obvious options like the earthing etc. as suggested by A73UK. This is basically the last remaining problem.

Barney thank you so much for those faxes, I will get back to you via email soon as well, the stuff on the carb is exactly what I was looking for, I will be taking of the air cleaner to be more accurate with my spray and hopefully it is not difficult to repair.

I will update with my progress the moment I am done.

Once more thank you very much you guys, I am learning everyday and that is fantastic.

Warm regards.

It's vacuum advance regulator, not vacuum pump

I hoped you kissed the scrappy for his random act of kindness

LOL

Not likely, this bloke is double my length and my width (x-jail warden) but clearly has a kind heart.

Hi folks,

Random Cut-out solved:
I eventually managed to get this final problem solved. Unfortunately in doing so I discovered a potentially new problem which is slowly creeping up on me. At least I am now aware of it and will see if the scrap yard fellow might be able to help me out again.

To get back to the cut-out, it seemed it was just another “slightly” faulty ECU (ignition module) again. I can’t believe how sensitive or prone to damage these little things are. Finding a good one seems similar to buying a lotto ticket

I let the car idle for as long as it could and eventually it cut out. I then replaced the current module with a new one I bought last week when I could not get the car to start for R250 (€23) - ripped off again as I can get them fairly cheaper now from the new people for around R160-00 (€14), new. After fitting this one, the car was able to idle for close to 30 minutes before cutting out again. At this stage the module was pretty hot. I had a different second hand one lying about that another fellow gave me earlier in the week to try and fitted that one. It then idled and idled until the little “Time to visit the fuel station” light came on and ever since never cut out again.

I was really chuffed about eventually getting this out of the way and I will definitely try to keep at least two good spare modules in the car at all times as part of my roadside rescue kit.

New problem creeping up:
In my quest to get a better hang of things and from a run-in long ago when I had an Toyota Corolla, I remembered it also cut out once almost like this after I went through some bad water puddles on the road – water in the distributor it was. So prior to experimenting with the modules as above, I took off the distributor cap and took a good look inside with a strong flash light. What I saw was a bit disturbing. It seems like there is a little bit of oil leaking into the housing. The only way for it to get in seems to be in the area where the distributor cam seems sealed and connects to the engine side.

I decided to take on a dangerous adventure, to me at least with my limited experience. I took the whole distributor off, marking everything I could beforehand and taking some pics as well. Slowly disassembled it and cleaned it well and dried it again with compressed air (there was oil on the little “pick-up” thingy with the two wire also), reassembled and fortunately for me, it fired up first time round. Late yesterday evening when I got home again, I checked the situation again and could see a drop or two has entered again.

I did not (to scared) remove the cam and all of that, to see if there is some kind of seal there, so if there is someone out here who knows of this type of problem and if it could be solved by replacing some sort of seal without spending money replacing the whole thing, please let me know, or perhaps there is some other neat fix my newbie experience is unaware of.

I did get a price of around R400-00 (€37) for a new replacement distributor though, but would be really proud if I could fix the current one rather.

It just really peeves me to think that the local mechanic did take it apart as well and I now know he probably just cleaned it, lied to me about it being water, and never told me it was leaking oil and that it would become a reoccurring problem. Naturally this means more future towing charges and service fees for him. I would never be able to sleep knowing that I treated someone like this.

Well that’s a wrap for now. Once more thanks for all the tips and help guys, you saved me from certain further abuse and heartaches.

Warm regards,
