Hi I was wondering else has had this prob,

Recently my 206 idles roughly to the point of soft shaking. It did have a missfire before which the leads, coils and sparks were change.

This was also after the thing refused to turn over... literally turn the key and zilch (anyone know what caused this?)

Since this has happened, I also get a severe loss of power and shaking when i'm trying to stay at a particular speed with the air con on?

Can anyone please help me?
