Hi everyone!
First post here, excuse my bad english as it is not my main language.
I have a Fiat Siena 1.2 ELX from 2004 with around 280k km and it has some problems:
1)Instable idling (never when I start it in the morning). This issue is constant
2)Hesitation when accelerating/releasing the trottle. Lack of power below 2000rpm. This issue is inconstant. It varies from day to day.
3)Low MPG
I took it to a mechanic that found a faulty Lambda probe. That could explain these symptoms.
But I was wondering maybe there are some impurities in the gas tank that cause the instable idle (that's why it never happens in the morning). If so, how can I check and repair this?
Thanks for your input!
