It's a Punto, something is probably malfunctioning, it's wise to check
Funny you should say that, on this punto every thing is malfunctioning girlfriend bought it on advise from her grandad, i had no say on it, for £1100 last year, so far she has spent £983 on it trying to get it right, New back box and centre pipe, near front and rear pads and discs, and some brake lines, new battery new top gasket on engine as it was leaking and still is, and 4 new tyres as they were all illegal when she bought it! and to top it all off now theirs a hole in the manifold which has the catalyst built into it, so it sounds like a tank, and the little ends are tapping like mad!
After spending so much on it i was going to make a project out of it and buy a new engine and manifold off ebay and have a go at doing it myself, but not sure its worth the effort.
