Hi All,

I'm new to the forum and wondered if some of you Punto experts could help me out here...

I recently bought a 51 plate Fiat Punto Go with around 49k on the clock. The car has a full service history and has been well maintained. However, it was due a service. My friend owns a garage and we changed all of the spark plugs, carried out a full system flush and oil change as well as adding a new oil filter. However, now the car is mis-firing whilst driivng in pretty much any gear. The strange thing is that it is irregular, some days it's fine, other days it doesn't seem to want to drive!

Having read other forums, I've been told it could be the ECU, could be the coils or could be the HT leads. It just seems strange to me that it doesn't mis-fire every time.

Can anyone shed any light or do you need more information?

Thanks

Mark

Hi New,

I had the same prob with my M reg punto, and changed lots of things before i got a Diagnostic check done on it. And it showed that the C02 sensor was not working. I bought one at my local car parts place about £26. Fitted it myself. Car has been fine ever since.
Hope this helps
