I have looked at several similar threads to my car's problem.
It is a K reg Uno Hobby 999cc with SPi. From cold it starts perfectly and initially sounds great. It starts to get rougher the warmer it gets. I have replaced plugs, leads, dizzy cap, vacuum to no avail although the vacuum did cause some improvement. Short journeys are fine but once temperature has raised car is a nightmare in traffic. It will stall unless I keep pedal down. If I do get heavy on the pedal, it kangaroos a bit afterwards.
I have also noticed that peformance at higher speeds (motorway) is way down and I struggle to get above 70mph. There is a bit of a tappety noise but only when I floor the pedal.
I have had timing checked and that is spot on after recent cam belt and tensioner replacement.
After nosing through my trusty Haynes I have come to the following possibilities:
Dodgy sensor
ECU is packing up
Throttle position switch
I'm leaning towards the last one as the spring clip was missing off the plug when I started to tackle the problem. I think the previous owner may have had a dabble.
I assume that only a FIAT dealer will have the correct kit to check the sensors or ECU.
I live in the Worcester area if you can recommend any specialists
Cheers
