Morning good Fiat people.

I've been the proud owner from new of a relatively trouble free Black Fiat Seicento Sporting for 9 years now. But working from home, I barely use it now and want to sell it. Thankfully it sailed through the MOT, but has a lingering issue that I'd like to fix before selling.

It starts and idles just fine, but when pushed - especially on a hill - it begins to struggle, jumping and jerking like crazy. It never cuts out but the injection light comes on when it's really jumping badly.

My local garage wanted to do all kinds of expensive work to suss out the issue. They put new leads on, as well as trying 2 new condensers with no real success. All roads seem to point to the lamba sensor. But is there anything I can do to check, rather than dump any profit from the sale into the wallet of another garage?

Many thanks in advance.

You could fit a lambda from a scrappy -- they're very easy to fit: 1 connector and the lambda unscrews. It does sound like the lambda.

If the car runs and accelerates smoothly when cold, its could be lambda, why don't the garage want to measure it?

Cheers

"condensors" ? or did you mean "coils", cos condensors are found in cars that have a distributor, and older type ignition with "points"

Apologies - I meant coils.

Update: got a known to be good Lambda sensor from a scrap yard and it made no difference.

So... before I sell it as is, any more ideas? If only so that I can pass this info to the potential buyer. I just want rid of it now.

I woulod definatley say the coil pack... I've had the same issue in a cinq, it had been sitting around, and the coil pack was arcing, but only if my foot was to the floor... For a temp fix, i covered the thing in water displacement, i.e wd40, to stop it from arcing, and it was fine for a fix while i took it to the garage... Try it and see what happeneds.

Now that sounds like a useful idea. It'll tell me if that's what's wrong for sure. Thanks for that tip. I'll let you know if it works.

....Should've said before, but you want to check the condition of the wires too, make sure they're clean and well intact... My friends KA had a jumpy ride, coil pack was fine, just the wires that were the problem... might save you a few sterling!

Check at night, in the dark, rev the engine and look for sparks where there shouldn't be any. ie outside the engine.

on a bit of a tangent when was the last time you changed the fuel filter? could be worth the 4quid. imho it could be a feed pressure issue and the usual suspect for this is the filter tbh youd expect it to do it all the time but electronics are a funy thing.

i thought sporting filters are more like £15
