Technical Uno Giving up on me

[nashy]

Hi There peeps!

The situation is like this. Last week tuesday i got stuck on the highway with my UNO 1.1 (Weber Carb). Figured it was the Ignition Module (Again):bang: , i went to buy the ignition module and the car was fine,I left the car parked in the yard since last week Thursday, i just started it up everyday and let it run until it was warm.

Then the problem started on Monday.The car would just die on me and not start again, i took it to a mechanic and he found that the wiress connecting the iginition module from inside the distributor came loose. so he took the distributor apart and fixed it and ever since the car has been really slow and it struggled to go up hills, when i drive and accelerate is hesitates and jerks quite a bit, the engine also has a really rough idle. Could it be the distributor

Please any advise would do as the car will be going to the dealership tomorrow. and i need it to drive like it.

Is the vacuum advance still working? Check it is still connected

Sounds like you did have wiring or connection issues (and perhaps not a faulty module) but it never hurts to put a new one in when you're having problems like this.

I reckon that the ignition timing is now wrong (not advanced enough) - possibly the vacuum advance is busted or more likely the mechanic removed the distributor to get a better look inside, and didn't time the engine quite right afterwards. I would diplomatically ask that he re-checks the timing and the vacuum advance, as Rayking said. Or of course, do it yourself - but you need a timing light (usually cheap enough when you can find them for sale!) Whatever you do, don't succumb to the temptation of tinkering with the carburettor... the ignition MUST be in perfect tune first! (don't ask how I know this - hours spent trying to reverse the changes made in desperation)

With the vacuum advance disconnected (and the pipe plugged so that the engine can idle slowly), there should be 5 degrees ignition advance, indicated by the notch in the flywheel lining up with the second pointer from the left (in the clutch housing window) under the timing light's flash (pickup on spark plug #1). Reconnecting the vacuum advance should result in an increase to about 12 degrees advanced (perhaps more).

If timing is incorrect, the distributor body can be turned after slackening the two 10mm nuts. This is a quick procedure - about ten minutes at most for someone who has done it before. I think your mechanic should agree to re-check his work. "Excrement occurs"...

Thanks for the prompt replies, will tell him to have a look, infact i will show him this thread so that he can check and try everything mentioned here.

Thanks again
